It has nothing to do with the RFC for a variant. It is a standard interface to 
communicate with the backend to generate vectorized versions of the functions. 
It relies on Vector ABI, provided by Intel and ARM, it follows the way it is 
implemented in GCC. There was an RFC for this long time ago which was accepted 
by the community and later implemented.
