How and when do they interfere?
If syn cookies are enabled and the queue isn't full, they're not used
so they don't interfere.
If the queue is full, they do interfere, but the alternative would be
no connection at all.
So I really don't see the disadvantage of enabling cookies by default.

Actually changing the value isn't the problem, but the Debian
maintainer isn't sure it's a good idea (but he doesn't know why).
