Users will not be able to use Mercurial as they do now. That is as much
a fantasy as Jed's gitifyhg. Let me put it simply: no modern VCS can
roundtrip a native merge commit. Not even git. Anything to the contrary
is fooling yourself.

You can get all the above workflow from Mercurial, as I've pointed out
before, but it seems that all the technical discussion was done by a git
contributor that repeatedly show no understanding of Mercurial
internals. So, forgive me if I think your "technical" discussion was
biased.
