No particular ceremony, as I'm treating these as bugs found by working
on the reference implementation (in this case, the Docker build
environment). Finding spec defects after approval is actually a pretty
normal occurrence for PEPs targeting the CPython reference
implementation, as some flaws only become apparent once you put
something to the test of implementation (as happened here).

Cheers,
Nick.
