Are vertex insertion and deletion also supported/accelerated?
What compromises are keeping this constrained to 32-bit? It seems like you could cut back on quantization error by increasing bits, but if you're doing some manual SIMD magic to get this performance I can understand sticking with 32 bits.
Not the author, but I assume that to make it work with 32 bits integer coordinates, some operation (like multiplications) need extension to 64 bits. If we want full hardware support on 64 bits CPUs, that's the limit.
