Since https://cabal.readthedocs.io/en/stable/file-format-changelog.html#cabal-version-3-0 , "Free text fields (e.g. description) preserve empty lines and indentation. In other words, you don’t need to add dots for blank lines."

Since 3.0 has been around for a long time, I'd like to start generating my cabal files with this cabal-version, and avoid adding the silly dots for blank lines, if possible. What's a good way to force hpack to select cabal-version 3.0 ?
