I've been using Linux for more than 10 years and I had no idea this was a thing lol.
But yeah after reading up on it I don't see the issue with giving someone this id (though I also don't see any reason why someone would need it). It's just a file on disk that can be changed at will with a kernel parameter.
Dual booting is an option, but without two separate drives (or sometimes even with windows on a separate disk), windows update will just nuke your EFI partition and do its own thing.
It's possible, but I probably wouldn't recommend to a beginner, as bootloader issues are usually not fun to fix (had to do it a lot when I was dual-booting back in the day)
