"After thinking about this, I'll handle the Perl License issue as part of bug 333932. That bug will entail reorganizing the license selection widget into sections to reduce clutter. I'll move the Perl License to a "legacy" section and hide that during project registration. During project edit, you'll see that choice only if your project's chosen it, mostly so you can de-select it :)."
