I went through the new bundle format doc and one thing I did not see
is any mention of subrepos.
Currently the bundle/unbundle commands completely ignore subrepos.
This is quite annoying when you have to share stuff with people who do
not have access to a shared web server.

It would be really neat if in the future we could create a bundle on
the parent repository and the resulting bundle contained bundles of
the corresponding subrepo revisions. Would that even be possible with
the planned bundle2 format? I saw mentions on the wiki of being able
to send a pony to a contributor. I would settle for being able to send
subrepo revisions :-)

Cheers,
