That is an enormous amount of effort: major kudos to him for being
willing to tackle it. I think that in some cases, such a practice will
not necessarily going to give the highest-quality result: the
"backporter" won't always have as much context about the bug as the
original "fixer", and may not be able to ensure that it is fixed properly.

I'm actually arguing against calling it "backporting" at all: the point
is that it is *more* urgent to fix the bug on a release branch than to
do so on the trunk, so we should refer to the process as "forward-porting".
Pragmatically, it is typically *easier* to forward-port a bugfix than to
backport it, because the "common ancestry" in the merge is more likely
to be helpful.
Of course, some kinds "janitorial" practices (e.g., tidying up
whitespace, imports, etc.) can make this harder if done only on the
trunk. That sort of friction is one of the reasons why change velocity
drops off on successful projects.
