Because that is a packet every 120 seconds that isn't required for me and 
for most people with sane NAT timeouts or accessing local servers.  It 
could also increase internet costs for those under "Per-Meg" payment 
plans.

Same is true with ClientAliveInterval.  They exist to resolve a problem 
that someone may have, but I'd hate to see the extra traffic by default on 
my work LAN/WAN where it isn't required.
