Codegen worked. I tested everything (both codegen and updated clj-kondo resource hooks) with avclj. For things that are public-api facing, I think codegen hits the widest possible audience. Internal to my libraries, I will now publish clj-kondo hooks with the libraries themselves. Codegen via ns-publics, btw, was https://github.com/cnuernber/dtype-next/blob/master/src/tech/v3/datatype/export_symbols.clj#L72 - and produces https://github.com/cnuernber/dtype-next/blob/master/src/tech/v3/datatype.clj.

Awesome! Yes, I think it's the most reliable method.

Unless you use something like the potemkin macro which enumerate all the var names explicitly

That one is relatively easy to support via hooks (we already have a built-one for it)

But code-gen surely works and needs nothing extra
