I suppose it's possible that that could turn out well.

The situation with Apple hardware feels a bit like the early days of Linux (including the fast pace of development). There was a time when if you wanted broad hardware support it was better to run an Alan Cox kernel than a Linus kernel. And the whole point of git was to have a system that didn't require one central blessed tree.
