If you're fine with a cryptographic RNG, then definitely. I'd even agree that cryptographic RNGs should be default. Rust made the right choice here.
But look at C++'s new RNG library. Go's random library. People don't want to give up the lightweight, fast defaults they have. Even Rust's canonical random library has an XorShiftRng. These are what PCG is competing with, and replacing all those weak RNGs with PGC RNGs would make them all much better.
