Creating blueprint assets/hierarchies with Python

In another thread it was replied to me that it wasn’t planned to be able to create BluePrint code using Python because full BluePrint APIs weren’t exposed. If that changed then it would be really useful being able to code visual BluePrints spaghetti algorithms with Python script code. Still in editor will it be possible to even translate existing BluePrints to Python scripting for further editing thru Python? Or is Python scripting working on existing BluePrints and not just for creating new ones so that full editing and so coding could be done thru Python then? If runtime support will be added in the future too that would be great too.
