Hi! It seems that `dump-decls` of GHC 9.12.2 misses instances. For example, I cannot find the `Functor` instance of `Data.Functor.Product.Product` in `tests/interface-stability/base-exports.stdout`. In the `HEAD` version it is present, though. Is this a known problem? Which `base-exports.stdout` files are reliable? The one of GHC 9.14.1? The one of `HEAD`? All the best, Wolfgang
