Great, then your choices are (a) try and probably fail to get your changes upstreamed and/or (b) maintain your own fork of git forever.

This is very much a "if you don't like X about your country, just move to a different one" kind of "solution". The costs are extreme to the point that pretending it's viable is insulting. Really it's just a way to silence legitimate complaints.

Probably unacceptable as many would have built tooling around the specific default behaviors.
