Sorry, apparently I even forgot its proper name, i meant `clangd::FeatureModule`. Nothing bad happened, we built this infra but didn't get a chance to polish and use it afterwards.
We wanted to migrate any non-core components into this bit slowly (clang-tidy, include-cleaner, even LSP features themselves) to both make clangd features more plug&play but also ensure less maintenance burden in the core infra.
