Only compiled extensions / compiled .so are affected, not pure Qml
apps as far as I know. And there is ongoing discussions on how to
provide the backwards compatible stack in parallel to 5.2 stack. It
started off in vUDS sessions and continued on the hallway tracks and
post vUDS. I'm not quite sure who is in charge  / implementing that
work. Maybe Loic can comment more?

We do need to land 5.2 soon, as we are fast approaching feature freeze
and 14.04 release....
