Hm, so I had to try the stopping thingie. At first it was cool that it stopped at 130% of stop signs I tested it on. Then I noticed another thing that explained a bunch of quirks
It seems this release is indeed mostly aimed at data gathering of some sort but I wish Tesla was more

forthcoming in the release notes about how it works (hint to EAP users that did not try it much yet - make sure there's nobody behind you when you are using it! you'll thank me later).

Also it is stopping for unmapped stuff, but mapped gives more of a head-ups.

I have shot a bunch of videos before having that late realization about the internal mechanics and I guess it would make no sense to publish it because I suspect it won't be released to general public in the current form anyway.
