This is not so; of SSH_MSG_CHANNEL_EXTENDED_DATA messages, connect-23
writes

   Data sent with these messages consumes the same window as ordinary
   data.

I don't know; I didn't write it - but I speculate it's to avoid
confusing people who know that in TCP, the FIN bit - the closest analog
to ssh's CLOSE message - _does_ consume sequence number space.
