I think it would be reasonable if it just forced you to decide about it. That
is reading the documentation, checkout only switches branches if the merge of
each modified file is trivial and only does 3-way merge if it got -m option.

It might be reasonable to requre that option for all cases, where there are
local changes and the branches don't point to the same commit and without it,
checkout should say something like:

  Cannot switch branches, because the tree is modified. You can apply the
  modifications to the target branch by using -m option, or commit them
  before switching branches (you can undo or amend that commit later if it's
  not finished yet).

The case with branches pointing to the same commit is for checkout -b,
reverting that command if you do it too early/by mistake/wanted branch
instead and for doing it with branch + checkout.
