 A primary design goal for IPv6 was plug'n'play zeroconf-type 
 automated setup of networks: connect computers and routers into 
 switches and have them figure out for themselves how to route 
 traffic by default without need of user/administrator intervention. 
 Basically, it was an identified failing of IPv4 that too much 
 configuration was required, and that the successor should "just 
 work" out of the box in simple environments with basic needs. 
  
 This is why essentially all operating systems have IPv6 on by 
 default, with SLAAC or similar address coordination, neighbor 
 discovery, route advertisements, and so on. The Linux kernel is no 
 different in this regard.
