I'm not buying into Apple's eventually-closed desktop computer systems - I don't care what the performance is. They've been slowly marching towards iOS's closed ecosystem model on the Mac and with an in-house CPU, they can effectively lock users out of alternate OS choices on their hardware. Buyer beware.
People buy mac to use macOS. Some will also use bootcamp for windows if VM is not enough for their tasks. And installing linux instead of macOS on a mac even sounds strange.
So - nothing to be aware of. Macs always were build to run Apple OS
