What about making the git fetcher default to nobranch instead
of branch=master?

Using a branch name made sense back in the days when projects were not

Having a default branch set in the git fetcher made sense back in the
days when there was agreement on the name of a development branch.

A branch in SRC_URI is just an optional automatic check that the commit
used is on that branch, it is not necessary.

BTW: In most cases a better check would be implementing #13303.
