[Fiona] Based on that logic rawdev should be deprecated.
But the community has agreed that it has a place.
And the common problem here is device exposure.
With a specialised service on top.

[Fiona] Can you point me to that requirement please?
We suggested it, but did not get community engagement and have 
dropped our generic API requirement, instead focussing on this specialised case.
