I know :) However, there are some open questions from Thomas' original
submission that still needs to be ironed out.

My point was that I know this patch needs work, so any feedback that get
it closer to a solution will help.
Pluggable storage may / may not add new requirements, but it is up to
the people working on that, some of which are Committers, to take time
"off" to provide feedback for this patch in order steer me in right
direction.
Work can happen in parallel, and I'm definitely not recommending that
people hold off on any patches that they want to provide feedback for,
or submit for a CommitFest.
Best regards,
Jesper
