That will indeed turn off customizations in ~/.hgrc. But the user will
also lose the ui.username setting which might not be what you want when
you make a commit :-)

Brodie Rao has been working on an a patch that will allow you to set
HGPLAIN to make Mercurial revert to 'plain' behavior:

  http://bitbucket.org/brodie/mercurial-crew-mq/src/tip/script-mode

It will disable localization and reset verbose mode.

However, it will not help you here: the user has mis-configured
Mercurial by asking it to load an extension that does not exist. The
warning will still be issued with Brodie's HGPLAIN patch.

I think the best solution is to teach your mode to ignore these warnings
From Mercurial.
