Something you said tripped a synapse.

No, this can't be safely removed.

I now seem to recall that this was added when sourcing /etc/zshenv was
exempted from NO_RCS.  If the system zshenv sets HISTFILE or SAVEHIST,
then you can get bad side-effects even with "zsh -f" unless NO_RCS
suppresses history file management.
