Exiting 1 makes it a lot easier to include a "guix lint" step in external
CI pipelines.

Hi,

Please expound a little bit. :-)
Could you also add a sentence under “Invoking guix lint” in the manual?

Yeah, though some lint warnings are more critical than others, and often
they’re just warnings, which is why ‘guix lint’ always returned zero so
far.

For clarity I would separate warning collection from warning printing.
So:
(let ((tty? …)
(warnings (append-map (lambda (checker) …) checkers)))
(for-each (lambda (warning) …) warnings)
(null? warnings)) ;return #t when WARNINGS is empty

I’d suggest something similar here.
Could you send an updated patch?
Thanks,
