I do find it reasonable, but I think 'upstream' has several advantages
over it.

* 'upstream' makes "git push" and "git pull" symmetrical. While there
  are workflows where it is usefull to have "push" and "pull" point to
  different branches, I think it is far more intuitive to have this
  symmetry by default.

* For newbies, the sequence "create an empty repository, clone it,
  commit and push" works like a charm with either 'upstream' or
  'current'. Today, the first push to an empty repository requires
  either saying "git push origin master" or "git push --all", both of
  which sound like black magic to the poor user who did not yet learn
  what 'origin' is and what a branch is.

* 'upstream' makes it easy to create a local topic branch, and let
  'push' send it to the master branch (i.e. have local 'topic-branch'
  pull and push to 'origin/master'). In general, 'upstream' allows
  workflows where you push to branches with either a different name or
  with the same name (by setting the upstream appropriately), but the
  opposite is not true.

That being said, I think the mode you Michael described at least
deserves to exist, even if I disagree that it would be the best default.
