I'll take a closer look tomorrow, but generally I've put all "syntax errors" under the :syntax linter, might make sense here too?

I was gonna do :syntax but I saw that there's :unknown-require-option. I can switch to :syntax if you'd prefer.

Ah alright, I guess it makes sense then, perhaps better for people who are going to add their own options or so

Can you add tests to see if the ignore hint properly works in case people are using custom additions to the ns form?

In trying to add tests, I've run into a quirk I don't quite understand. When parsing the namespace declaration, ^:clj-kondo/ignore and other metadata are in :meta on the nodes, not in the meta of the node. Is this due to lift-meta-context not being called on it or something?

Not sure, but if you want me to take a look and finish up the tests, I'd be open to that of course (and you'll still be a contributor of the PR git-wise of course).

I've pushed my failing test, so go for it.

Fixed via other PR
