I haven't really loved Mac OS in a while, so I could see you could want the very nice Mac hardware but a different operating system. I never really did Windows-on-Mac much, besides some very occasional Boot Camp usage, but I did run Linux on a couple different Mac laptops for several years.
I don't think it really makes much sense now though... no particularly good reason not to just get a Dell XPS or something in that ballpark for your Linux or Windows needs and avoid the hassle.
The sheer absurdity of running Linux tools on WSL inside Parallels inside a Mac host might be worth something, too. (Or actually, can you even do that, with two levels of virtualization? I seem to remember this is an issue, maybe specifically on the new ARM chips.)
