And I've waited for a response from the difftool/mergetool maintainers
at first, so I waited with my reply till now.

Yes, merge.keepbackup was never documented, we shouldn't have to keep
backwards compatibility for such undocumented behaviour.

People which noticed that the documented mergetool.keepBackup didn't
work, had to look into the source to find out that merge.keepBackup did
it, so I see no problem with changing it. They rather should have
reported it anyway.

Ferry did it right with fixing this inconsistency.

Yes.
