Rebuilds for new Perl?

[Ville Skyttä <ville skytta iki fi>]

There have been some "Rebuild for new Perl" commits lately for perl-* 
packages, apparently using the dist-f9-perl koji tag.

Some questions:

- Is Perl 5.10 scheduled for F-9?
- Does Perl 5.10 require rebuilds of all/some/which packages?
- Should all maintainers of perl-* be doing these rebuilds?

Thanks in advance.
