Currently CPAN.pm has a special logic to make sure that if a requested package is found in the core perl distribution and in another package, that another package takes the precedence if its VERSION number is the same or higher than the VERSION number of that package in the core perl distro.
Now I working on a helper package for mod_perl CPAN modules (to reduce the craft in Makefile.PL) and I want it to be on CPAN, but also include it in the mod_perl 1.0 and 2.0 core (also living on CPAN). I foresee a problem with CPAN.pm, as it's going to see the same package in 3 different packages and which is going to be picked by CPAN.pm is undefined, since we have no special case logic for mod_perl-core packages. And we don't want CPAN.pm to try to install mod_perl 1.0, when I just want to fetch that single package.

My recommendation would be to not include the helper package in the two core packages, and to just add it as a dependency. Even if CPAN were changed in the way you suggest, it wouldn't work properly with people's stock CPANs, and it seems bad for mod_perl to depend on a certain version of CPAN.
