Off the top of my head, no, though it came up in the course of a
convesation on #guix recently, and it reminded me of advice I've gotten
in the past to just ignore a particular check on a particular package.

Yes, this! :)

Maybe something like:

(define-public thispackages
  (package
   (name "thispackages"
   ...
   (lint-overides
    (list
        ;; The upstream name is actually "This Packages", not a typo.
        "typo in description: 'This Packages' should be 'This Package'")) 

And then guix lint would hide or ignore things that would otherwise emit
the strings listed in lint-overrides ... or something like that. Maybe
exact match, maybe get into a little pattern matching, not
sure. Implementation is not my strong point here. :)

You might also want to add a guix lint check for unused overrides
(e.g. something that no longer triggers the issue, either fixed upstream
in guix lint itself, or some other way).

No. Maybe in some cases this might make sense, but was not what I was
suggesting.

Yeah, my suggestion was mostly about trying to address aspects of point
2.
