One potential side benefit of this type of work: vendor kernel drivers tend to be insecure buggy pieces of crap. Vendor Treble drivers will surely still be insecure buggy pieces of crap, but they might be sandboxable. If Google really has its eyes on the Magenta kernel, I imagine that Treble will be runnable in user mode, so I bet it really will be sandboxed. This would be a huge win.
