This is mostly explained by the fact that there have been a *lot* of
changes, many of them discussed in private emails.

Can you re-state those, or give a link to them?

I'd really like to get to a point where unprivileged containers can start
using filecaps - at this point if that means having an extra temporary
file format based on my earlier patchset while we hash this out, that
actually seems worthwhile.  But it would of course be ideal if we could
do the name based caps right in the first place.
