Those generalizations are uncomfortably sweeping.

What Samuel just described is one of the messaging patterns that Zaqar
implements and some (members of the TC?) believed that this messaging
pattern was the only pattern that Zaqar aimed to implement.

Some (members of the TC?) formed strong, negative opinions about how
this messaging pattern was implemented, but some/all of those same
people agreed a messaging API implementing those semantics would be a
useful thing to have.
