roi was initially written when most of the --value / --cost infrastructure was either absent or in its infancy. As a result, roi attempted to do its own very ad-hoc "convert to a single cost" thing -- which is no longer needed, and in fact fails miserably sometimes, as shown by #2190 .
This hopefully makes roi interact with --value/--cost in a more straightforward way.
