Not entirely sure I follow. Extension frames are support-or-discard,
yeah? So what proxy is going to understand the frames well enough to
fragment them, but not enough to realise reordering is bad?

I do see the earlier point about fragemntation, though. Maybe it would
be better to include a "do not coalesce across this boundary" marker
that's more than just the frame boundary.
