I already talked to dlg here, but that obviously cuts you out which
isn't good :/

well, you can over the console, and preferring existing states is the
right thing to do imo:
-(D)DoS-Traffic won't match a state, prefering states means that your
 legit traffic has a much higher chance
-ruleset evaluation is MUCH more expensive than state matching

not sure whether your product is the extreme outlier here; if it is
then the "you have to ifdef it out" is perfectly acceptable imo;
if it isn't we might need a button (shrug). the fact that nobody asked
for a button or the like in a decade makes me tend towards "not
needed".

me neither. things are significantly different now than they were 10+
years ago when bob & I chose "ipintrq full" as trigger. the congestion
trick isn't as effective any more as it used to be since the arrival
of MCLGETI - which overall is much more effective, and less selective
at the same time. the two should cooperate.
