Microsoft seems to have deleted all their old blog posts around it (at least all the links to their responses 404 now), but...
In 2011, they were going to require it to be enabled for all products if they wanted to announce Windows 8 support.

But their original goal was for it to never be allowed to be disabled
For unplayable, Rocket League had very good Linux and macos native builds.
Epic required them to delete support for those operating systems as part of the acquisition of Psyonix
I get wanting to move away from "master," but why in the world didn't we use "trunk"
It was already a standard name, and it fits "branches," etc.
