Why base library changes are only discussed on GHC issue tracker and not on the libraries@ list?

7 Jul 2021

      For example

- https://gitlab.haskell.org/ghc/ghc/-/issues/20044 ByteArray migration
from primitive to base
- https://gitlab.haskell.org/ghc/ghc/-/issues/20027 Changing Show String
behavior

Why they are discussed "in private", I thought libraries@ list is where
such changes should be discussed.
