We spoke about this on IRC, but there is at least synthpod that 
implements patch extension properly. synthpod itself does not yet have a 
stable release though..

I finished mod-host/ui support for lv2 parameters through patch:Set/Get 
a few days ago, and now working to finalize Carla (so v2.3 which will be 
out in 25 days should support this much better)

This has been a chicken&egg problem. Host support was lacking, so most 
plugins just used the old ways. And even the existing plugins were/are 
not always correct about this. It is improving, but someone has to make 
the jump to kinda force the rest of developers to support it too.
The OMK plugins are a great start, they all use these new APIs -
