Priorities change though; in particular, security is a rising priority. So it's not inevitable that funded compiler development must focus on wringing every last optimization out of software that might perform well enough if it were simpler. Organizations like NLnet and ISRG, for example, could fund work on getting to a usable Unix-like system that's entirely compiled with one of the simpler C compilers that don't exploit undefined behavior so much. They could justify it with the argument that security is best achieved through simplicity at all levels of the stack, including a simple build toolchain.
