Huh, I've been using a directory named exactly like that for basically the same reason. Still not sure, how I feel about applications randomly deciding to throw a folder into there. I guess, it is much better than MuseScore deciding, fuck it, here's a folder under Documents/, though.

And while I'd prefer applications not to just randomly create folders in general, I can also understand that it's a somewhat big ask from average users, where they'd like your random folder to be stored.
