If the cons of WireGuard are that it gives the users less freedom to 
make mistakes, then I'm all for it.

I don't really get why the iface bindings should be accomplished at the 
WireGuard level. If I get it correctly, it won't be safer than it 
already is.
WireGuard just has to provide a secure and standard network interface. 
There are other full-featured, clogged VPNs out there that can even make 
you the coffee, I'd like WireGuard to stand out and stick to the 
original "UNIX tools philosophy": do one thing and do it well.
