However, in that use-case, whenever the parent repository is pulled/updated, it also updates the subrepo, which is cumbersome because developers have to go through each of the subrepo to update them back to the tip. That "Daily Development" scenario of not updating subrepo when updating parent repo is not possible at all in Mercurial (couldn't find options for it), yet it's the most common one for us.

You should have a look at Martin Geisler's onsub extension
(http://mercurial.selenic.com/wiki/OnsubExtension). It is bundled with
TortoiseHg (and I think it would be useful to bundle it with mercurial
core too). It lets you run commands on all your subrepos. For example
you can do:

    hg onsub update

And all your subrepos will be updated to the head of the default branch.

BTW, we usually bottom post on this mailing list.
