I've brought this up at the previous sprints but if we're going to be
making a generic storage format then is it worth it to combine this with
the blackbox format?

It seems to me that they will both have to solve the same problems
(locking, generic format, etc.). If we put some thought into this now,
we could perhaps get some server-side features and maybe extension

My thinking is that by having a storage layer, extensions could do
queries like:

select * where type = 'remotebookmark'

and even adding that data so that core doesn't have to have a hard-coded

Perhaps it's too early for this, though.
