Well, dpkg and apt allow it for starters.
The idea with the perl packages is that the src:perl binary packages
offer an older "stable" version of some modules while a newer version is
packaged separately and gets installed earlier on the Perl search path
(so it overrides the src:perl version when installed.)
This has been the case for ages with the src:perl packages Providing
an unversioned virtual package. The change here is that the virtual
package is now versioned, which would simplify lots of dependencies
that currently read like (for instance)
perl (>= 5.16.1) | libscalar-list-utils-perl (>= 1:1.24)
