Junio just said "but that is fine", so afaiu he's not against allowing
it per se. It's just that him and the other frequent contributors don't
have this particular problem, so if *they* fix it it will
a) Not be done with enthusiasm, and it would indeed drain enthusiasm and
   happiness from the project.
b) Perhaps not be done the way those who want this feature would like it.
c) Take another scarce resource (time) from other, more pressing issues
   which may or may not affect your workflow too.

Junio also suggested what's likely to be needed for this to work "properly", ie, an extension to the git protocol to let it transfer symref content.

Since empty repositories have HEAD pointing to refs/heads/master by default, you might get away with a simpler implementation.

Not stupid, but most likely unusual. Optimizing git for your needs would imho be a bad idea. It's perfectly fine to use a tool for something else than what it was intended for, but then you'll have to live with the fact that it *will* have a few shortcomings and that you'll have to work around them or fix them yourself.
