This is just an index issue to be updated frequently, as frequent as a PR merging some of these into existing / new categories is merged. We can have a significant performance boost if these are merged just by sharing conditionals. Avoiding some allocations would also be a secondary benefit of merging these.

Pending group:

inherent_to_string & inherent_to_string_shadow_display → functions

[Centri3]

We should disregard most of the restriction lints listed here unless they really cleanly fit into other groups (First thing that comes to mind that really wouldn't is pattern_type_mismatch). Once allowed lints aren't ran, having restriction lints in their own pass should be more efficient on its own

[blyxyas]

I just updated the list striking all restriction lints, a case-by-case selection can be done later.

[J-ZhengLi]

How about the inherent_to_string siblings: [inherent_to_string] and [inherent_to_string_shadow_display]? Which could be grouped into functions I think?

[felix91gr]

I've just opened a PR to update the Cognitive Complexity lint's documentation: #14915

I thought that perhaps that can be of use for this issue, since I see this lint still listed without a strikethrough in the original post
