Ok, but consider the prior email with kan about MFC's after an 8.0 release.
Since you must be able to run 7.x binaries on 8.0, then you can't MFC any
symbol changes from 8.0+ back to 7.x. The symbols are basically frozen in
7.x after 8.0 is released.
Sounds like a bug. :-)
I realize that is a rather simplistic view, but the reality is that we want
the best of both worlds: we like having active feaure merging, and we like
having multiple active branches with releases after a .0. In fact, having a
.4 on one branch after a .0 on the next branch seems pretty central to our
world view. As many downsides as library versions had, one upside was the
ability to do this. I need to go read Alexander's e-mail, but it seems that
really this limitation shouldn't have to exist.
