You dont have to "screw around" with iptables. The kernel wont load the 
conntrack modules/code unless you actually try to load stateful 
rulesets*. rp filtering on by default I'd also argue is the better 
default setting, for the 99% of other usecases :-P

With quagga I would tend to agree - but as you I have not used it ages 
and things do change for the better over time -- occasionally.

* you CAN configure your kernel to always load it, but that is silly.
