Ok - allowing ptrace to set the full 32 bits of the PKRU register seems OK
then, and is 100% equivalent to using WRPKRU, right? So there's no implicit
masking/clearing of bits depending on how many keys are available, or other
details where WRPKRU might differ from a pure 32-bit per thread write,
correct?

Yes, it's the same.
