How each client answered
| Client | Version | Verdict | What happened |
|---|---|---|---|
| curl | ngtcp2/1.11.0 | Pass | Tolerated it and continued. The specification permits this but does not require it; a client that rejected it would also be conformant. |
| quinn | noq fork | Pass | Handled it: stayed inside the stream limits and announced the stall (0 STREAMS_BLOCKED for bidirectional, 1 for unidirectional), which §4.6 recommends but does not require. |
| aioquic | 1.3.0 | Pass | Tolerated it and continued. The specification permits this but does not require it; a client that rejected it would also be conformant. |
| chromium | build 1223 | Pass | Tolerated it and continued. The specification permits this but does not require it; a client that rejected it would also be conformant. |
| quic-go | quic-go v0.61.0 | Pass | Tolerated it and continued. The specification permits this but does not require it; a client that rejected it would also be conformant. |
| quiche | 0.30.0 | Pass | Tolerated it and continued. The specification permits this but does not require it; a client that rejected it would also be conformant. |
| neqo | 0.31.1 | Pass | Tolerated it and continued. The specification permits this but does not require it; a client that rejected it would also be conformant. |
What the clause requires
Stay inside the advertised limits. Respecting them is a MUST — §4.6 says "Endpoints MUST NOT exceed the limit set by their peer" — but announcing the stall with STREAMS_BLOCKED is only a SHOULD, so a client that stays silent is still conformant.
Judged against RFC 9000.
