Erm, I would like this feature as a downstream user.

I'm not asking for this to be the default or even easily available.
However, when you know you've based a downstream tree on what you know
to be a volatile base, it would be very useful information to have.

Right at the moment, I maintain a <branch> and a <branch>-base and
simply cherry pick the commits between the two to do the right thing
when I know my volatile base has changed.  It would be very helpful to
have a version of rebase that new my base had been rebased.

Basing on a tree I know to be volatile is sometimes a development
decision I make as a downstream user ... I'm just wishing the tools
could help me handle the problems better.
