I don't believe that the imported version numbers will be recognized by PAUSE. See the PAUSE documentation, and also this note in Perl::Critic::Policy::Modules::RequireVersionVar:

=head1 TO DO

Add check that C<$VERSION> is independently evaluatable.  In
particular, prohibit this:

    our $VERSION = $Other::Module::VERSION;

This doesn't work because PAUSE and other tools literally copy your
version declaration out of your module and evaluates it in isolation,
at which point there's nothing in C<Other::Module>, and so the
C<$VERSION> is undefined.

This may cause problems for downstream users who specify per-module dependencies. It's up to you whether you want to support them; some people feel quite strongly about it, such as "Anonymous Monk" above.
