For the most part probably not, but Microsoft cares a lot about backwards compatibility so I imagine some of this code still lives on in Windows
Though you should take this with a grain of salt, since I’m saying this as someone who 1. never looked at Wine source code 2. used the Windows API only once, for a very small program 3. is still learning programming, so I wouldn’t call myself a coder (yet) either
Not really surprising considering that (IIRC) it’s the default on the Gnome variants of Ubuntu, Debian and Fedora
But keep in mind that voluntary data tends to be pretty skewed
