https://quarry.wmflabs.org/query/26090 shows the linter counts on metawiki for ns0.
While the numbers look high, there are some mitigating factors:
- The tidy font bug counts are high because of lots of signatures on proposals, election pages, and the like. And user signatures have a lot of this broken usage. There is no point fixing those old pages where the only thing that will change is a color of parts of a user signature
- metawiki is a wiki with translate extension enabled. So, a lot of issues might be in the translated blobs.
At this point, it might make sense to make the switch and have editors fix any other pages that look broken.
Unless there are objections, I'm going to make this switch on May 2nd during the morning SWAT slot.
