Routers that support the Selector Protocol could check signatures.

Interests with the same selector would be exact matched throughout the
network at any node.

Interests with different selectors would not match on all routers, but
they would match just fine on routers that supported the Selector Protocol.

Basically, everything you want works on routers that support the Selector
Protocol, but routers that don¹t want to support it, don¹t have to.
