There are ways to game the infestation too.
One thing you can do for infestation prevention is to lay power cable across all overhead mountain tiles. They don't seem to spawn in rooms that are all power cables. This will make the room less beautiful, and if you have it linked up to a battery now creates a big risk of explosions/fires. So I just make sure that if I'm doing this, I don't link it to a battery. Or I have a fusebox mod installed because it's silly not to have circuit breakers you can research and build when you can build space ships.
The other thing you can do to prevent infestation problems is to dig out large indoor areas you don't intend on using for anything other than infestation bait. With enough of these you can effectively bait the infestations to occur where you want them instead of where they would be most problematic.
With regards to the OP the game has always been about tricking it, the storyteller system just works that way. You want the game to think you are not doing well so that it screws you over as little as possible. In whatever ways you can't trick the game you are incentivized to be minimalist. Everyone could have super wealthy super expensive bedrooms but the raid scaling isn't worth the mood boosts. You don't want to have many colonists incapable of violence or useless in fights because every colonist contributes to raid scaling. You don't want to have amazing high quality plasteel melee weapons because they contribute to raid scaling far greater than they actually perform better than steel, and are as equally useless against mechanoid raids. Sometimes you don't even want to grow too much at once because the game will be more inclined to blight you and screw you out of everything.
