Curvetools/ Non destructiv workflow with curves in B3D

I miss a lot of tools working with curves in B3D. Meshtools are often better, so often i convert curves to mesh back and forth. BTW I also love the way it works in 3dmax just adding a edit poly and keep it non destructiv. Is there a way to keep it non destructiv in B3D via an addon like animation nodes atm ?
Or are there and Plans for 2.8+ to improve curvetools or non destructiv Workflow with curves? Maybe via everythingnodes?

no one? anyone an idea?
