There's some discussion on the RFCs and mailing lists about creating new backwards-incompatible OO APIs for the core libraries which would eventually replace some of the legacy mess.

Can you link the RFC's/Threads? When you're not familiar with the PHP dev ecosystem it can be hard to find the meaningful stuff.

I think this is the way to go about it. And if earlier versions want those kinds of APIs they can implement them in packages.
