You thinking that TT-30 won't work because it'll be able to communicate "I'm supposed to be a 240V connection; if you're seeing less than say 200V that's too much of a voltage sag, so you probably better shut down to prevent a fire"?
Yes, something like that. I just don't know how much they locked down these new adapters. The TT-30 is unusual in that it is rated at 30A but only at 120 V. For example, cars built in 2013 and 2012 have a limitation with 120v supplies. They won't charge at anything faster than 20A when given 120V. Here, it could be worse, since the highest adapter Tesla supports at 120V draws 16A instead of the 24A that a TT-30 could supply. Ah well, no use worrying about what might happen, we'll just have to try it out.

Perhaps the two dummy pins will be used in the new European UMC to provide three phases.

Just a minor correction, All the NEMA 6/10/14 plugs can either be 240V from a single phase connection or 208V from a three-phase connection. However if the new UMC and its adapters are indeed "smart" they can distinguish between those two cases.
Technically, it's not new. The European UMC has been different from the NA one since it was introduced - mostly because it supports 3-phase. In addition, there is a special UMC for Norway and other grid networks that are not grounded neutral WYE 400V L-L / 230V L-N.
Well, Cosmacelf, if you're going to get all pedantic on us, you should have the facts:
Fein (not Fain) and Dremel are tool manufacturers, not specific tools. Using either of those names to refer to a specific tool is a bit sloppy and not very descriptive. The guy in the video clearly fell into this trap... but so did you.
The tool used in the video is generically called an "oscillating tool." Fein makes a few versions of this type of tool. One of them is called the "MultiMaster" (not "Toolmaster"). Dremel also makes this type of tool.
The specific tool used in the video is clearly labeled "DREMEL" along its side. I think it's safe to call it a Dremel, although, again, it's not terribly descriptive. In addition, most people use that word to [sloppily] refer to high speed roto-tools made by any manufacturer, rather than oscillating tools.

Give me some sugar baby
So for a TT-30, one will need to build a 14-30R-TT-30P adapter cable.
I am thinking that when my Model 3 arrives, and if/when I drive out in the boonies, I should carry my JESLA instead of buying adapters for the new UMC. Will get a full 40 amps on a 14-50 too.
I have one leftover too and that's what I'm doing. With a full line of adapters- and 14-30 with the neutral sawed off (thanks @Cosmacelf ^_^)
You mean to use a TT-30 receptacle out there? Maybe @Cosmacelf and others can opine, because I've never tried this myself, but I thought using a 240v stub on the UMC wouldn't work if the source is 120v
(and...really? TT-30 is 120v @30A (24A sustained) =2.8 kW..you may get 5.5ish? miles per hour charge instead of the 4ish with the regular NEMA 5-20.. maybe just need to get this). Do you think you'll really need it -eg staying ooout there in a camping overnight- or are you a 'have all the bases covered' sort of person? Not judging just curious about the use case.
Yes, you can indeed give a 240v Tesla adapter 120v and it’ll work fine. The UMC is picky which of the two hots gets the 120v and which gets neutral though.
A TT-30 is indeed a rare beast, but there are use cases. Some commercial buildings or event complexes will have TT-30 in their parking lots. Some campgrounds only have TT-30s.
This is the kind of thing that I don't expect to change. The Model S/X MC is picky about where the hot and neutral are and the Model 3 MC probably will be too.
Ah, so the resistance in the adapter just says how much to draw, but doesn't 'inform' the UMC whether to 'expect' 120 or 240? I didn't expect that robustness. Thanks, good to know.
