FWIW these patches stand on their own whether we accept the wireguard
patches or not. Put more plainly - please do not read me applying this
set as an endorsement of the larger plan..

The specs themselves are gaining maturity. I think adding a YNL spec
for wireguard would be quite nice. Whether we should be converting
the kernel code and uAPI to take advantage of the auto-generation is
a completely separate conversation. If you're not anticipating many
new additions in the uAPI there's little to be gained.
