IIRC Linux (at least) syncookies only come into play when you are being
syn-flooded (i.e. when the kernel has to start dropping syns).  Having
them enabled at other times has no impact, so there's rarely (if ever) a
reason to disable them.

I don't speak for anybody but myself - that's enough trouble.
