This is really a personal preference.
For example I really *hate* merges, they clutter everything.

git diff is all you need to check if there are differences, merges tell
you nothing about that, and merges canj *hide* changes you were supposed
*not to* bring from one branch to the other.
So really this is pretty much personal preference, and each maintainer
should be allowed to use the scheme they prefer.

(and co-maintainers or proven packages should be careful of keeping the
same style IMO)

cherry-picking should have been used in this case.

About this I wonder if we should have the preference stated somewehere
in the git tree for each package so that it is clear what is the
maintainer style.
