The rule here is

alert http any any -> any any (sid: 1;)

Should it match on the stream end packets?

@catenacyber are there cases where only at the end of the stream, with the pseudo packets we detect the app protocol? I guess we could, if data stays un-ack'd, then stream terminates, FFR will force handling of un-ACK'd data, detect protocol.

It matched in master on sid 2, in OISF/suricata#12169 it won't match.

this I think makes sense, the sig is

drop ip any any -> any any (msg:"Drop all else"; flow:stateless; sid:3;)

If there are no "real" packets, why raise alerts?
