Just expect it not to be approved; the examples you cite were added before rules were tightened up, so prior precedent won't get a game accepted.

Yeah it 100% is because the rules got more strict because of newer restrictions in game approvals due to maintanance cost and extra effort to run the site. It's not the community size as community size shouldn't factor in the reasoning to run the game, if a game has a WR that anyone can achieve within a few minutes of playing the game, people will just play the category as a meme, I mean look at Break Dirt in Minecraft (Classic) lol https://www.speedrun.com/mcc#Meme_Categories
