> Out of curiosity, what is your approach? Carrying around a `bool Scalable` flag?

We keep some state around that tells us if we're in a scalable mode. But this doesn't work if we want to be able to vectorize both for fixed size or scalable at the same time for the same target. Not sure if you're considering this scenario (e.g. Advanced SIMD + SVE-256)
