Perhaps. Other developers have suggested that before.

The problem is that everyone wants to make --ff-only the default, and
then we start to get into a tricky situation, because what should these
do:

  git -c pull.ff=only pull
  git -c pull.ff=only pull --merge
  git -c pull.ff=only pull --rebase

One of these will always fail, when it shouldn't.

I proposed a solution for that, but is has been ignored.
