Isn't the same true with a point-point API? When you add a third device
to the vlan you're going to have to break the tap-guest link, and insert
a proxy in the middle.
I thought with a point-to-point API, you would not actually be inserting
any third device.

That's a fair chunk of functionality you just lost then.

True, but is it actually useful?

Short-circuiting two guest devices probably isn't. Adding host devices (like recording packets) might be.
