While I do agree with your point, when I take over a bug I test all
supported versions to see which ones are buggy. Now you can choose to
patch the latest and backport, or to patch the oldest and up-port. It is
a choice. Mercurial is designed for up-porting.

In fact, "up-porting" is usually better, because you don't have to think
if you must downport or not. Versión "n+1" is always a superset of
versión "n". So you "up-port" *ALWAYS*, automatically (mostly) via merge.

If you choose the backporting way, you must take a decision about what
to backport, for every single changeset. And god forbids you forget
something in the process...

I agree you have a point when you write a new functionality for the
latest version and LATER somebody decides that a particular changeset
must be backported. Or a fix not planed for old versions is re-scheduled.

Would be very nice if the HG cherrypick extension would be more clever.
Of if mercurial would recognize that a patch is already manually
committed in both lines, and cope with that gracefully when merging. I
am sure we are not alone with these issues, and I hope somebody is
actually doing something about it.
