This would de-universalize ports that he still needs to have installed universal for other reasons. As he said:

I assume where he said "dependents" he meant "dependencies."

perl5.16 *is* in the recursive dependencies of OpenSceneGraph. So enforcing -universal for recursive dependencies of OpenSceneGraph will result in perl5.16 becoming non-universal. And this may then turn out to be a problem for some other port he has installed that still needs perl5.16 to be universal.
