Is there any guidance regarding this?
I mean, on one hand, I think users (plugins dev mainly) might be upset 
if this change is happening so close to 2.0 release and on the other 
hand we don't want to wait ten years for this to happen, especially if 
this brings QGIS more easily on mobile device.
If QGIS 3 is brought as the "mobile" release, it might sweeten the pill.
