(#16812665)
It wasn't a migration as much as a bottom-up rewrite of the entire bpy and big chunks of blender itself. Most of the bindings are generated by makesrna at compile (compile compile?) time which is fairly simple once you go deep diving into the sources.
It actually takes a fair bit of shenanigans to get hand-coded bindings into blender, my last(?) patch was bindings for the kdtree and I had to do some convincing to get that accepted. I'd guess that 99% of bpy is generated bindings.
If they stuck with python 2 when they started the initial overhaul they'd probably still be using it since artists are very vocal when their scripts break.
