Yeah, good point. That said, even if it's not an open standard with a 
fixed system architecture, you have things like the x86-64 cpu 
micro-arch feature levels to work with, eg 
https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html. Making the 
supported versions narrow enough to not burden development but not so 
narrow that it discourages use and therefore discovering interesting 
bugs isn't an easy job.
