You are right. The hostid travels in the connect data and is just as
forgeable as the hostnqn, so this cannot stop a determined host from
claiming another host's identity; it only keeps the lookup consistent
with the identity a controller was created with.

I have posted a v2 that rewords the changelog as a correctness fix and
drops the security framing.
