It would be nice to have it so that I could extend my logging to this tables 
with little effort, but if not, I'll revert to my old friend - "started".

If I do that, according to the man pages, that won't load my other non-ct 
modules ("...restricts the set of modules loaded by shorewall to those listed 
in /var/lib/shorewall/helpers") which isn't what I want as I have various other 
modules (not ct-related) which need to me loaded and these are listed in the 
modules.* files.

I don't want to do that either because when I upgrade shorewall, the chances of 
new capabilities existing in that version which won't be included in the 
existing "capabilities" file are pretty high and I am not about to run the 
update or regenerate all my capabilities file with every shorewall update. 

Besides, if that turns out to be the case, then I am going to have another 
shorewall message telling me that my capabilities file is out of date - 
lose-lose scenario!
