Actually, with all the industry support for Linux, I'd be more concerned with minix (ironically, as Intel me runs minix), free/net/openbsd, haiku, new experimental oses (like new stuff written in rust), new hypervisors (like xen, but new projects). Of course, as long as "Linux support" means "load signed extensible, Turing-complete bootloader that can do anything" - people running another OS can continue to that, with no help from the hw in securing their fde encryption keys...
