Why does the p0f-analyzer.pl script exists?

I see that the p0f tool is capable of caching a specified
amount of request, and then reply to queries issues through
a unix socket.

This in native C-language, which often means reduced size
and increased performance with respect to perl's
p0f-analyzer.pl.

If I understand correctly, when you are running p0f with -Q
(unix socket) 
option, there is no easy way to get the tcp source port and
put it in 
the query packets to get the correct cached result. I don't
know if there 
is MTA or smtp implementation to cache smtp client tcp
source port.
