Common support cases for our Gerrit admins stems from users creating
projects without an initial empty commit. The absolute vast majority
of end-users do want an initial commit in their newly created projects,
but sometimes misses to check the "Create initial commit"-checkbox in
the UI. When failing to do so, the situation may be a bit problematic
to remedy for the end user since:
* It is not always clear why they cannot push reviews to their newly
created git.
* It is cumbersome to create an empty root commit for casual git users
* Direct push to refs/heads/* is not always permittable
At our company we have yet to see someone creating an empty commit and
do not want it.
