Sure, let's do that. The trend overall is to integrate the compat stuff
more closely into where the native implementation lives, so this
would just follow that trend.

I think with Christoph's latest patches, about half of them are
going away as well.

Right, the network headers pull in almost everything else through
multiple indirect inclusions, anything we can do to reduce that
helps.
