I don't think you can make that decision single-handedly. doesn't it depend
on the situation, and shouldn't individual users and/or developers be able
to make that decision themselves?

And still, you're adjusting the assembler check, you need to adjust the
runtime check. This won't do what you think it does. It's not a runtime
check and doesn't check host runtime abilities, just host build abilities.
