Have you noticed if any of the calendar protocols allow for recording an appointment without specifying a date?

Consider a haircut that will take 45 minutes & will invite two people (me & the barber), but the day/time is still undecided. Perhaps that sort of appointment can park at a placeholder date with infinite capacity until the real date is scheduled?

There's a draft that's been floating around and renewed multiple times over the years called VPOLL which is supposed to do basically this, but it's very tricky to get the edge cases sensible, so it's still not totally done. Generally one party offers appointment times and the other party books one, which simplifies it considerably.

I really like the idea of free-floating scheduling.

I think that’s called a draft :)
