    Any reason to not remove maybeprofile() from _runcommand() ? Can it be enabled
    after reposetup() ?

Yes, if it is configured in the repo-specific settings (.hg/hgrc), for example, then it would be missed if
maybeprofile were removed from _runcommand(). Additionally, we’d need to wrap other callsites of
_runcommand(), such as _checkshellalias(), to maintain the existing behavior.

(Resending this because I didn’t CC the list; sorry for the duplicate message.)
