I'd say yes, we can do that. We are supporting other SIMD instructions that we don't test in CI, so if it works on qemu during PR review then I think that's enough. Clearly there's a potential for issues here when we gain more SIMD support that is not exercised in CI, so maybe we need a test strategy longer term where we can run things under qemu at least in a weekly CI job or so (qemu in regular CI isn't feasible, too slow).
