That's just a design decision, right? There's no need for a "default" or 
"root" subvolume.

It should be rather easy to change btrfs so that you first have to 
create a "storage pool" which combines disks for btrfs, and on top of 
that you can create "filesystems" which are just subvolumes.

The creation of a "storage pool" could be very similar to the current 
mkfs, just without the creation of a root subvolume.

A new, simpler mkfs would then just create a subvolume on top of the 
"storage pool" that can be mounted.

Kaspar
