<blockquote> At some point older versions will not be supported and have unpatched security vulnerabilities</blockquote>
I don't think this is valid argument for RHEL. They maintain and fix perl by their selves AFAIK.
<blockquote>module updates won't run on older versions of Perl</blockquote>
I didn't see much modules, which won't work on perl 5.10 and even 5.8 (but I didn't check some huge frameworks)
