Both projects have stable ABI requirements. And the lead time to get the change propagated out to applications is long (>5yrs) even longer with the Enterprise distro's. As developers we can all just pass the buck but this doesn't help users in any reasonable time fram. It is not as simple as just making a patch or pull request for their upstream code bases.
