The alternative is to leave the working copy in a totally broken state. I'm not
sure why that would be preferable.

My hope here is for a reduction in the pain/time taken out from real work in the
OSS developer world while people are moving to DSCMs - particularly for those
that have to learn/move between both Mercurial and git. Requiring people to be
aware of this gotcha and to use solutions like hooks seems to raise barriers
rather than eliminate them.

Cloning and working with multiple repositories locally is a particularly
Mercurial workflow. I see this issue as a barrier to those who've cut their DSCM
teeth on Mercurial and are trying to use git. Would detaching HEAD really be a
problem in git workflows?
