Like as in the customization tab? Seems much more preferable, yeah.

Not sure anyone wants this feature, really, if I'm honest.

uh... i want it. people want this feature i guess that's only me and this guy?

Then collect support for it? Right now I see this one PR, by one person, and one supporting comment. I don't recall asking a single discussion asking for this feature in 5 years prior to this.

What I do keep hearing about is how mania perfects are "notoriously difficult" and thus am asking myself who would put want to put themselves through this mod, which is where the "not sure anyone wants this" comment comes from?

who would put want to put themselves through this mod

From what I've seen there's a lot of high accuracy players that like setting perfect 1m scores in easy maps, or even across maps from all skill levels.

Easy map example -- Beginning | Hard map example -- Lost Umbrella
(Despite low umbrella being a 6* map, skilled players can easily set high acc plays and get very impressive max:300 ratios, due to the map mostly consisting on chordjacks/jumps of triples and quads, which are not that difficult to get high accuracy on, compared to something like a constant stream of notes.)

While it may sound insanely hard due to how tight the max 300s hit window is, perfect 1m scores are not something impossible to achieve, and there's a lot of players willing to put the effort of a true 100% accuracy play. Just look at any low difficulty map and you'll find a lot of 1m scores across all keymodes.

Also the description of the perfect mode is "SS or quit", and the current behavior of it in mania does not lock you to only getting a perfect score (yellow 300s still drop your acc). If this pr goes through as a toggle for the current PF mod, I'm not suggesting that a 1m score requirement should be the default for it, but it's also worth considering.
