The “More Hats” mod is never going to be sanctioned as all of the hats in the game files are there for future, official DLC and events. If someone makes some entirely new models and textures for hats, they might make it in but the current hats everyone is raving about will be available through official releases and will almost never be given away for free.
The Bot Improvements mod might make a fundamental change to the difficulty of the game - and as FS have said something along the lines of “We don’t want the bots to be too good as we want people to play together” Then the bot improvements are unlikely to see the official realm.
I’d rather ALL mods were in the modded realm, but then I’m a bit of a purist - and I completely agree with @Belsebull in that I’ll kick anyone who is wearing a stupid hat on the wrong character. Shove off into the modded realm.
