I wonder would it be viable to provide this support within the current AP=
I=20
using a Storage adapter?=20

The adapter could delegate non-version requests to an ordinary storage=20
embedded within itself, but handle all methods that relate to versions on=
 its=20
own. This adapter could be used to add a versioning capability to all=20
storages that do not currently suport it.

That would mean that version state is independant of normal state. I thin=
k=20
(but Im not sure) that is a good thing.
