To the question of "why," I'd think the answer is in the discussion
held
in the devel@ mailing list linked below. Generally, sharing the
storage
pool in order to avoid running out of space in one location when
there
was still space left in the pool due to "bad" partitioning choices
was
seen as a benefit.

From btrfs-quota(8):
On the other hand, the traditional approach has only a poor solution to
restrict directories. At installation time, the harddisk can be
partitioned so that every directory (eg. /usr, /var/, ...) that needs a
limit gets its own partition. The obvious problem is that those limits
cannot be changed without a reinstallation. The btrfs subvolume feature
builds a bridge. Subvolumes correspond in many ways to partitions, as
every subvolume looks like its own filesystem. With subvolume quota, it
is now possible to restrict each subvolume like a partition, but keep
the flexibility of quota. The space for each subvolume can be expanded
or restricted on the fly.
