Thanks for clearing that up. I'll try to be more clear, next time. :)

Well, if zsh -n is intended to be used for checking whether a Zsh
source file can be parsed (is it?), then yes, I think that's a bug.


As for your other points: I don't really have anything to comment on
them, as this function hasn't been my idea in the first place. I
originally just had a note in the newuser .zshrc telling the user to
use `exec zsh` to apply changes, rather than `source ~/.zshrc`.
However, in workers/48026, Oliver expressed apprehension about this,
to which Bart, in workers/48031, suggested a different solution, which
I ultimately grew into the patch submitted here. Perhaps the three of
you could discuss this further?
