Thanks for letting me know, I wasn't aware. This is non-obvious but seems quite handy. 

It appears to have changed to Default: Empty now though: https://cabal.readthedocs.io/en/latest/cabal-project.html#cfg-field-optional-packages, Default value: Empty. 

(https://www.haskell.org/cabal/users-guide is quite out of date, cf https://github.com/haskell/cabal-website/issues/8. Perhaps it corresponds to cabal-install 3.0.0.0, I don't know.)

It probably needed an optional-packages line to replicate the default. But I have removed it based on your input.

I think I have pulled all from your darcsden-darcs-2.14 for the moment, except for ghc 8.6-related changes which I'll come back to when things have settled.

Best,
