when used pfctl should log any changes to state of FW

I have been working with OpenBSD since 2.6, have deployed it in many roles. 
Have hacked authpf to have authpfnoip with ip functionality (there is a reason!). 
So I have some experience with the OS...mostly as an implementer/admin not a dev type.

Motivation:
I am configuring a 'segregating' Openbsd based firewall that I want to 
maximize the auditibility/accountability on/for. 

Question/Suggestion:
So why does pfctl not appear to (I could not find a command line option - nor previous request)
 log to syslog every command (who when what exit status) that changes anything within
 the pf context such as : rules, table contents, states?

I don't want the detailed changes that may occur within pf - just establishing accountability.
