We can use non-flavoured SPIRV for that, no? Once the rest of the toolchain
bits are in place, that'll work as well, and will offer neither ASM nor
builtins. Surely, if there's actual some groundswell of opposition to ASM,
folks will organically migrate. I'd say that's preferable to trying to force
users to do anything, which seldom works well.
