Ah, maybe the help text is ambiguous; I interpreted that as saying it
"only installs the package in the current directory [not in some other
directory]".

Perhaps rename --only to --no-reconfigure or so?

cabal install
  --reconfigure    : run "cabal configure" with previous options
before install [default]
  --no-reconfigure : build and install, without reconfiguring
