I think that's absolutely right.  Note though, that it's not until I'm ready
to publish my work that I'd be ready to collapse things down.  IOW, while the
work is still in progress, I do care about each revision.  When I'm ready to
push though, I think those individual revisions are much less interesting.  Of
course, this "collapsing" might happen more than once during the lifetime of a
branch (e.g. hey-can-you-help-me-with-this, ready-for-review,
i've-responded-to-your-review, ready-to-land).

+1

Yep, although one person's signal is another person's noise. :)
