Or more generally some sort of "allocation cookie". The way this might be implemented might be, like you say, by allocating from some dedicated blockgroups on Ext-like filesysems.
But you could also envision a more generic "subvolume" like logic for managing this (allocation pools in zfs, certain block device subsets in btrfs, ...)
