It certainly could be. OTOH its so easy to do with subunit(*) I don't
know that we need to embed the logic in bzr itself.

*: bzr selftest --subunit | subunit-filter --no-skips | subunit-ls | tee
failing.list

OTOH it would be smaller to type :P

My goal with subunit is to relieve projects of needing to individually
reinvent such facilities though. If bzr can use subunit to get a short
option like you describe without special casing internally I think that
would be great. Hmm, perhaps file a bug (on bzr) and I'll look at it in
some idle moment.
