RFC-9000: CONNECTION_CLOSE frame contribution to congestion control

[Jaikiran Pai]

Hello everyone,

I was looking at the QUIC congestion control RFC 9002 
(https://www.rfc-editor.org/rfc/rfc9002) section 3 and it states:

"The types of frames contained in a packet affect recovery and 
congestion control logic:
...
Packets containing frames besides ACK or CONNECTION_CLOSE frames count 
toward congestion control limits and are considered to be in flight."

So as per RFC-9002, it means that ACK and CONNECTION_CLOSE frames do not 
contribute to congestion control limits.

On the other hand, RFC-9000, section 12.4 has a Table 3 
(https://www.rfc-editor.org/rfc/rfc9000#frame-types) which states:

"The "Spec" column in Table 3 summarizes any special rules governing the 
processing or generation of the frame type, as indicated by the 
following characters:
...
C: Packets containing only frames with this marking do not count toward 
bytes in flight for congestion control purposes; see [QUIC-RECOVERY]."

However, in that table, the CONNECTION_CLOSE frame isn't marked with the 
"C" character and only the ACK frame is. Is this an oversight in this table?
