For me, the issue is willingness, not permission ;-).  Reviewing a patch includes somehow indicating changes needed to apply it 'today', and a revised patch is the best way.  Please say whether the header changes are in 3.6 only (in which case a separate 3.5 patch is needed) or in both.  'Commit ready' means that you believe a core dev could (and should) download, apply without issue, and commit when satisfies.  I should do so within a week if no one else does.
