Well, I don't understand the concern. If you've just made a graft, why
would you forget about it? And is it important that the user be
reminded at every step?
"hg summary" would be a good place to display additional information,
but I don't think commands like "hg status" or "hg diff" need to be
changed.

I guess there's a tension between providing a light-weight command
that doesn't touch the rest of the core (like "hg transplant") and
something more sophisticated that addresses the use cases of a larger
base of people.

But other features such as named branches are now everywhere too, not
just in "hg branch" and "hg branches".
