I am not seeing it as nonsense. The OP made a valid observation, PGUSER
is not used by the program even though the docs say it should be. If
what you say about is libpq is also valid for the other programs listed
here:
https://www.postgresql.org/docs/12/reference-server.html
then the docs probably to be gone over for them also:
https://www.postgresql.org/docs/12/app-pg-ctl.html
"pg_ctl, like most other PostgreSQL utilities, also uses the environment
variables supported by libpq (see Section 33.14)."
