It's good that they're not just going to plop the thing in there in a degraded state (with probably worse performance [and DoS resistance] than the current out of tree/dkms distributions of wireguard).

Yea, indeed, I'm really trying to get the mainline version to have the same performance and security characteristics as the out-of-tree module version.

(And after it's mainlined, the out-of-tree module will only exist as compatibility for older kernels, and I'll have some scripts to automatically extract a mainline kernel into a backport.)
