The obvious counterpoint to your statement is that if your mentality held sway, we would never have had Git and would still be on SVN.
To put another way; I HATE git, I LOVE Mercurial, but Git won, it's ubiquitous and Mercurial is not that much better.
I hesitate to criticise it, but I don't think such an environment would be polished. A frozen environment is one which can't be improved, so will naturally stagnate. You couldn't achieve a state of being "extremely polished" because those who cared to do the polishing would be denied the ability to do so because it requires change in order to do so.
Having one thing doesn't ensure at all that it will be polished. In fact, it's more likely that it will stagnate.
Hg and Git are both GPLv2.
