Hi David (@dholmes-ora),

Thanks for the suggestion!
We're open to changes in the API as suggested by the community. The users need to be aware that `push_paired`/`pop_paired` or `pushp`/`popp` will fallback to the legacy push/pop instructions if the CPU does not support APX features.

Thanks,
Vamsi
