Of course, it should be rare. git history goes back 15 years already. There are scant few bugs that old. There is a tree with even older history that Rob Landley still has here: https://landley.net/kdocs/fullhist/ It does make git blame research a bit easier for those rare and extremely old defects. > > The nature of the fix should ideally be optimal for > > backporting, but I believe that should not stop any > > consideration for the standalone fix itself. > > I'm not sure to follow this. I think it comes down to defects in current need to be fixed. Describing the base commit that is being fixed is useful for backporting. I believe it's not reasonable to ask the author of a fix to research how it could or should be backported. > Sometimes non-bug fixes that block > backporting a bug fix have to be backported as well.

Sure, but the non-bug fixes that may also need backporting to enable easy backports of the actual fix should not be described in the Fixes: <commit> as those are generally easily researched from a command like: $ git log <commit>.. <files in fix> by whoever needs to backport.
