dual lived modules

[Marcela Maslanova]

Hello,
I'd like to ask on your opinion on dual lived modules in
our distro. I knew that Mandriva has the main perl package
and also provide rpms of sub-packages, which are easier to
update. They are using patch that allows them override the
core modules. Also debian has perl core and sub-packages
as separated modules.

This question was raised again in [1]. I suppose there would
be conflicts after every update of main perl package, which
could complicate it.

So I'd like to hear pros and cons on this issue. Thanks.
