If I'm reading the code correctly, the cli calls cabal-client:commands.js and runs cabal.client.addCabal. When that executes at https://github.com/cabal-club/cabal-client/blob/b23a45b7e2a96fea9820193ebbf0c2d1e37f77f0/src/client.js#L134 it doesn't call cabal-core's isHyperCoreKey https://github.com/cabal-club/cabal-core/blob/9a0f6e7395ed707d1f348b0049ce20f199cfcfe9/index.js#L224 to verify that what we are passing is a valid key (just a string). My guess is that this is so we can deal with aliases?
