Yeah, it’s fine if they’re different across devices - just so long as they’re consistent between boots.
Now-a-days, this is actually almost a universal feature in most full-bodied linux distros (accomplishing it through one of several ways). It just usually goes unnoticed (as your typical linux system has a single network interface, or a lan link + wifi at most). Having a career in networking, I definitely notice 
(having spend a good amount of time with systems running many interfaces).
