That's actually puzzling, because when I run "zsh -f" for 3.1.6-pws-6,
all of hashcmds, hashdirs, and hashlistall are set.

Does your /etc/zshenv unset these, perhaps?

The manual is only partly correct, because ...

... it turns out that the implementation of "correct" causes hashing to
occur, in which case the setting of hashdirs is respected independently
of hashcmds.

Given that "correct" silently causes hashing to occur, I think the patch
that I posted is a necessary one.  zsh-workers:  Should the doc be updated
to reflect that "correct" overrides "nohashcmds"?
