Yes, I see from the code what it does, it's just that I think that the
option is obscure and very rarely used. It's not shown in the --help
output, though, so I guess it's not a big problem.

I don't think this name is better. "cabal install" runs the solver and
installs all dependencies, while "install --only" only copies the
files (like "make install"/"runghc Setup.[l]hs install").
