To me, that means that before anybody even discovers the WSDL to find
out what the specific interface is about, that there exists a
pre-specified interface that can be used to bootstrap the richer
stuff on top.

Yes. There is a prerequisite for this, as expressed for "predictably
evolvable architecture"
in [1]. 
"CSF PE4. Stagger "features" in a standard so that even software that
implemented only the     minimal features in the standard can interoperate
with another software that implemented more features"

The idea is that if the features can be staggered (separated into
"modules"), then
a handshake protocol can learn about the supported standards/interfaces, and
their
"level" so that an entity can decide whether to interact with another
entity, and 
to what degree.
