G04-MQ: Yes
Rationale
The known-peer deployment can partition connection populations across additional endpoints and routed subnets; QUIC has no mandatory global connection coordinator. This architectural decomposition does not make one connection or one server scale without limit.
Assessment method
Documentary analysis
Source context
Primary specification / explicit profile inference
Outstanding qualification
Measure partitioned endpoint populations, per-connection path state and shared bottlenecks. Endpoint selection is provisioned, not a discovery service supplied by QUIC.
