Configure cabal bash autocompletion after installation

I wonder if it's possible to configure cabal autocompletion after installing cabal with ghcup.

I found this bash autocompletion script in the repository:

• https://github.com/haskell/cabal/blob/master/cabal-install/bash-completion/cabal

It's okay if this is not in scope for ghcup but I thought it would be nice to have an even better configured cabal setup!
