Not that I remember. Most likely the reason was that initially I was playing
with
different ways to place raw images (subvolume with a raw file with btrfs
snapshots vs.
just the raw file with COW-copying for snapshots), where for some variants a
different
file layout *could* be nice. But only in theory.

Probably not. There isn't all that much available.
Given that path based storages apparently already expect this to work in a
specific way
in some of the other storage functions outside the plugin (see Dominik's note
about
`get_subdir_files`) I think this patch makes sense.

^ So if we wanted to do anything else we'd probably need to override even more
of
`Plugin` (iow. override code from the *grandparent* class) for not much gain.
So yeah, I think the patch is fine.
