using queues and keep state

Hello everyone,

i'm using openbsd-6.2 as a home router gateway separating the internet 
from a dmz (httpd, mail, wlan) and an internal network.

I would like to use queues to establish bandwidth policies for traffic 
to my web and email servers and the rest of what goes on.

As an example, when a http request comes in, i really want to control 
the bandwidth for the response via a match out on $extIf statement. And 
maybe even the incoming request via a match out on $dmzIf.

In the past i've used a mix of match and pass rules to make that happen, 
but found that unless i set no state on my pass rules, the answer 
packets do not get evaluated on any outbound match rules.

Unfortunately using no state makes the rule set rather cumbersome and 
hard to read.

Did i overlook something or is that the way to do this?

I just looked again at man pf.conf and the book of pf, but don't really 
see any mention of keeping state in conjunction with bandwidth shaping.

Could someone enlighten me in this regard?
