That's a shame (and it is also a shame to waste a single letter option without documenting it!). I still would encourage you to avoid -P. I think there is user confusion by "parent" having more than one meaning even within btrfs. And I feel it also tends to perpetuate the mistaken belief that snapshots are somehow "special", and different from other subvolumes (rather than just a piece of information about how two subvolumes are related). It also allows -P to be used one day for the "search by parent UUID" feature. Given the constraints, I would suggest -n. It is mostly arbitrary but it is the second letter of snapshot and also the first of "not a snapshot". Thanks for considering.
