worth keeping this particular one while not discussing any other
alternatives at all. If you'd rather keep this information, it would be
better off to have it to an "Alternative approaches" section.

It was relevant because it was the most acceptable alternative found, and
we *still* didn't think it was an improvement over the status quo.

We don't generally significantly edit PEPs when accepting or rejecting them.
