The --cabal-lib-version= flag currently takes a specific version number. It could easily be like --constraint= or like cabal install "foo < 2" and take a dependency or a specific version number.

I just tried to figure out how this flag behaves now in practice, and it seems I can specify any version as --cabal-lib-version and I don't get any error message. Ranges still don't seem to be supported.
