Model Y Hitch Receiver: Rise Limit Question

I have been having a discussion with a friend who owns a Model Y. He pointed out that there is a 0.75" rise limit with the stock receiver, which I confirmed here:

The Model Y hitch receiver supports a ball mount with a length of up to 8.5” (22 cm) and a raise of up to 0.75” (2 cm). Please note that ball mounts that do not meet these requirements cannot be used.

I know the Model X had this same limitation, but it was a limitation of the removable Bosal receiver, which could bend out of true when loaded with any measurable rise. That was partly because it goosenecked out from below the bumper, and partly because it was a shaft and socket held in place with a pin and a few bearings. But why does this limit still exist on the Model Y? It appears to be a fully welded receiver without removable parts, and it seems odd that this restriction still exists.

My friend suggested a reason for this: Tesla just copied over the towing requirements from the Model X. Considering the odd limit (0.75"), I almost believe that. If I owned a Model Y, I'd probably just drop the bumper to check out the mount points and the way the receiver is built, but I don't, and my friend lives a few states away. He'd also probably kill me if I tried to drop the bumper on his Y.

I'm open to any thoughts on this, especially those of you who have towed with it. Are you just lucking out with trailers that don't require a ball rise?

I've towed my 2500 lb (as loaded) camping trailer over 3000 miles with no problems whatsoever.
I lucked out I think. I use the maximum .75" rise and my trailer is level at that height.
I don't understand the restriction either, but wouldn't be surprised if it was just copied over from the Model X.

My trailer is a Flagstaff T12RB hard-sided fold-up trailer. I use 500Wh/mile as my planning figure and it seems to average out pretty close to that figure, sometimes less, at my usual 65 mph speeds.

Can someone recommend a ball mount that meets the 8.5 in length and 0.75in rise specification and where to purchase? The ones I commonly see have 3 to 4 in rises. Thanks.

All of the 2" drop hitches I've looked at are also listed as 3/4" rise when you flip them over. I don't see the length dimension listed on them though.

I tried a Reese kit but the ball was mounted on the low side and impossible to get off. This was noted in the comments but I couldn't believe a manly man such as myself wouldn't be able to get it off. DOH!

I got the Reese 21792 drawbar/ball-mount and a 1" ball. Most, but not all, model dimensions are on the Reese site. And sometimes they're wrong. The 21792 is ~ 8.75" 'long' (center of pin to center of ball opening) not 10.5.

The rise limit is for two reasons: the first being the ball height puts the ball at the standard height of about 19”. The tongue weight limit would prevent any need for a higher mount.

The second would be the ball interfering with the tail gate although not really a problem.
