I'm wondering if a gems `require_path` field is really necessary. To
what extent is require_paths used by others? I know I use it one of my
projects, and for a long time I thought I could not do without it, but
now I think I see a reasonable alternative.

So is it possible... Could we eliminate this field and standardize on
the convention of a project's 'lib/' directory? Doing so would
trivialize the relationship between $LOAD_PATH and the location of
gems and grant us the usual benefits of convention over configuration.

Does anyone have a scenario necessitates configurable require_paths?
Or at least makes it extremely awkward to do without it?
