I don't know if it's too late for that group. Macs are fashionable and I think people will feel they're being treated poorly if given a Windows laptop instead.

You're right on with WSL2 providing a standard usable environment though. Windows and Mac developers both need a ton of handholding to get started and WSL2 makes it a lot easier to hand them a wiki page and expect fewer 1:1 calls to tweak setups.
