A small ramification of this change will be that I will need to do something like add a feature-bit to cpuid for detecting if HC_DYNAMIC is supported on the backend or not. The current v1 design doesn't suffer from this requirement because the presence of the dynamic vector itself is enough to know its supported. I like Avi's proposal enough to say that its worth this minor inconvenience, but FYI I will have to additionally submit a userspace patch for v2 if we go this route.
