The API permits protocol-invalid limits above 2^60, and its core advertisement behavior lacks direct verification.

…imit Lets a caller raise the connection's own MAX_STREAMS advertisement above the transport-parameter-configured default, for cases like WebTransport's anticipated-streams API where an application knows ahead of time that it wants more concurrency than the default allows. Monotonic: lowering the value later has no effect, since QUIC stream limits can only increase. zero_rtt_rejected's assertion that the limit matches the configured transport parameter no longer holds once a caller can raise it before the handshake confirms, which is exactly when the anticipated-streams API supplies it; relax it to allow anything at or above the default.

Not for Interop 2026 scoring: anticipated-streams.https.any.js isn't in the Interop 2026 WebTransport set. Firefox needs it for anticipatedConcurrentIncoming{Uni,Bi}directionalStreams (Bug 2007825), so after the Interop-related PRs is fine.
