isnt stuff like that going into the game later on anyway, even if nobody here ever talks about it? i also think thats the case for like 95% of the esv
Well, even if we were to think that Toady might have put things like the minecarts in without it being an ESV winner or talked about, which doesn't seem likely, since I don't recall it being in the old Devpages, then that doesn't mean he would have done the things people had talked about doing with minecarts. In the course of the 34.08 hauling release, Toady seemed to be pretty obviously reading and considering the things people had discussed and reacting to them, accordingly.
Just because Toady might be thinking of doing something vaguely like what people are talking about doesn't mean that there isn't something that people can argue out through discussion isn't going to make what Toady makes better.
If you have a quote from Toady where he's talking about how taming/training/creature domestication from worldgen of creatures is categorically or algorithmically handled by means other than just using common domestic tags or other tags we already have, I'd like to see it. Otherwise, there's no reason to believe it's something he's actively considering at the moment, and that he'll simply not work on it again unless there is some reason he is forced to do so in order to solve some other problem.
