That seems pretty dangerous if the packages replace standard or EPEL
libraries/components.   I'd have expected them to have some sort of
namespace concept for dependencies to keep the sets of packages
completely independent.   That is, I thought being independent was the
point.   Shouldn't you be able to have multiple versions installed?
