we do have some out-of-tree usages, but nothing in the tree, apart from tests, use this infrastructure yet.

yes, we basically should have a new feature-module, from that new feature-module we can contribute a tweak. this tweak can look at all the diagnostics in the AST, find the ones that intersect with users selection, and if they're from clang-tidy emit a code-action that inserts `` // NOLINTNEXTLINE(check-name)`.
