There's a lot of games that have a sort of boring standard (SC2's 1v1 ladder maps are all same-y, nobody competitive plays Smash with items on, etc.) and the fact that you see this pop up repeatedly in unrelated communities should probably tell you something.
IMO, when you have a game with sufficiently deep mechanics, wackiness tends to obscure that depth, resulting in an experience that's less interesting rather than more. Like if you added Mario Kart abilities to football/soccer and suddenly the winning team was getting regularly blue shelled, I don't think it would improve the experience, even if initially it'd be hilarious.
Now maybe it's still worth it to have "party game" modes in some cases, I'm just saying that these modes might not have legs, so to speak, and thus may not be worth the dev effort if hardly anyone plays them.
