I get not wanting to open the can of worms of having to review evidence of people trolling, and having to differentiate between "playstyle vs griefing". It also puts a lot more work onto support where they're now having to dig through reports when a new player messes up. I get it, we don't need that.
What should happen though is changing how the boss works specifically in public lobbies, or potentially just all lobbies (but my guess is speedrunners won't like that). There's no reason at all why a public lobby needs to pray before the first set of fungus are dealt with, and I think this makes the perfect opportunity to lock praying at statues until that is over. The second beneficial part of this is that it also helps solve a bug that griefers will abuse, where praying on the final tick of fungus will completely bug out the boss, where middle will close instantly and causing a guaranteed wipe.
