@francii, if you can confirm:

1. that there is a test that covers that error for z/OS, and
2. any comments in the code associated with generating the error above do not misrepresent the rationale for why `-p` is unsupported on z/OS,

then I'm good with leaving it at that.

Otherwise, we should make this into an NFC patch that adds the test/adjusts the comments.
