My issue is very simple. Don't say you are going to sell me something, demo it, and then not do it. If they never even mentioned the capability back in 2021 and it came out today, I would be like "oh well" and wouldn't care because I wasn't promised anything. If you are going to advertise something as a basis of sale, demo it, and then not deliver, in whatever format or method (steam, etc.), get ready for some legal headaches.
This applies to all the features previously mentioned. And it is quite apparent the 2021 MCUZ was a supply chain bastard (beta) version because they only made enough for 6 months or less worth of production on a low production vehicle (about 6400 of them max).
