OptionalbroadcastThe transport may deliver messages to more than one peer. Informational.
OptionalobjectThe transport carries JavaScript objects without string serialization
(structured-clone-grade), so non-JSON values such as Date, Map, and
undefined survive. Transports that JSON-serialize should report false.
Informational: the core does not branch on this flag.
OptionalremoteThe transport can carry bidirectional remote-reference request traffic.
OptionaltransferThe transport can forward transferables with sent messages.
Capabilities available on a message-level transport.
