Lead sheets is a good idea. Unquestionably a helpful and good resource for musicians, and what's the trouble of it really? It would take less time than a complicated and reduced-for-playability piano arrangement, because if you already know the chords it's just to note them down, and the melody line is something you'd need either way. And with lead sheets, practically all instruments can play the sheet, without loosing some crucial part of the song (given that a chord instrument is at your service).
Much of the purpose of a lead sheet is to make the rhythm changes understandable for the performer, and also making it possible for chord instruments & bass to join accompany the lead, and also to encourage improvisation.
Not all songs are the best for lead sheets though, just like how not all songs are good for piano arrangements (mlf, I'm lookin' at you).
Lead sheets are a great way to learn as well.
I'm jazz, so even when I play piano, lead sheets are better than normal sheet music. Much more fun, often more mentally challenging, and more free as you can improvise over the same rhythm changes.
Oh, and I have this sheet here of Relic Song - which could be translated into a cool jazz waltz:

Lead sheets should definitely be accepted on the site in my opinion.
Oh, and damn, it's nice to see there are more saxes than just myself!!
