GCC 12.1 Released

This is a valid position for application code to take, but library code IMHO generally should not be in the business of dictating architecture support unless it is doing something hardware-specific (e.g. if your library provides fast lock-free data structures, it's fair enough to say "the hardware must support certain atomic primitives," if your library does float math, it's fair enough to say "the hardware must conform to IEEE 754," and so on). Thing is, there's a lot of library code out there[citation needed], and it's hard to say with absolute certainty which libraries are getting used on more esoteric hardware configurations.
