FWIW my thought was that most e.g. RISC-V users will be specifying a CPU (a collection of ISA extensions), using and they already had to do that when they compiled the program so they would know the name that clang recognizes.  It seemed less common that someone would want/need to specify a set of ISA extensions manually for a target, but an important capability to have available.
