On the "early release" unit we had last February, they did not have the ability to be daisy-chained.

Has anyone received the 14-50 wall connector yet?

Indeed. Tesla Sales is stuck in the 1990s. Only email access (often takes days to get a reply). You get an online tracker once it ships.
It does have a smaller cord to the car, so don't expect a higher rate to be possible.
Opening it would likely void the warranty as well. Why would anyone ever buy this, at the same price as the other, if they were expecting to use those advanced features?

I can think of two reasons:
1. It is the only code compliant way I am aware of to put a pigtail on a Wall Connector. Even if you don't care about code compliance, it sounds like from the manual that it has a thermal temp sensor in the end of the whip to the receptacle which is a great safety feature.
2. It has a thinner cord to the car which may be desirable for some (the one on the basic Wall Connector is a beast).
Note that some folks live in temporary living arrangements (like an Apartment or Condo) but they want the convenience of a Wall Connector. So a plugged in option may work really well for them.
While I don't think there is much application for load-sharing two cord-connected wall connectors (since code won't allow two 14-50's on one circuit for EV charging anyway), I DO think there is a good use case for being able to flip a switch to tell the Wall Connector to limit itself to 32a (in the case where you have only a 40a circuit feeding it).
But if you purchase it to comply with code, then you open sealed "do not open" box and change the non-documented settings, what does that do to the UIL listing and following code? If the house burns down because the load sharing doesn't really work, Tesla isn't going to stand behind it.
I agree it has a place, that's for sure. Especially if it has thermal temp sensor in the pigtail. But I question purchasing it for un-documented use.

Yeah, agreed. If there is not a documented procedure in the manual for turning down the max current then you are right, it likely is not supported (which also means not code compliant).
I am mostly curious right now if the cover is removable in the exact same way it is on the regular Wall Connector and if the rotary dial (or any other switches) exist on the PCB. Once we know this and have pictures of it then we can debate what they might do and whether they are supported or not.
If they do exist but are not documented then perhaps we could hope Tesla choses to revise their manual at some point and document allowed uses. ;-) (not holding my breath)
In the unit we had in February 2018, I believe it had the dials and dip switches. We actually had to open the unit to change the dip switch setting because it was set to 120 volts instead of 240 volts. The faceplate came off exactly the same way as the regular wall connector. Once we changed the dip switch, the unit charged fine at 40 Amps. The included documentation didn't mention anything about changing any of the dials or switches but we had a regular WC manual which indicated what things did. At the time, we wondered if they all came off the production line with the wrong settings and that could've delayed their release to the public since they probably had to recall them to correct the settings.

Life is good!
I added the power cord to the regular WC. I didn’t want to give up my nema 14-50 power outlet. Finding a plug to use with 6 AWG was the difficult part. Connecting the cord to the WC was just like attaching regular house wire except it was to a plug. Wire from the power panel to the Nema 14-50 is 6 AWG too.

FYI, I emailed Tesla and they asked.
They confirmed that this version of the wall connector does not have the ability to set the amperage and that it can not pair with other wall connectors.
It is ONLY for use on 50a circuits they said.
So a very targeted use case.
Plug and play.
So we need to help make sure folks with 40a circuits don’t try to buy or use this.

Does anyone know if this wall charger qualifies for LADWP's charger rebate?
I contacted them to find out but they didn't know either since it was so new. Just that the existing hardwired wall connector qualifies.
