It's possible to build a kernel with 50 network drivers, too.  That 
doesn't mean they should all be "default y".  The kernel build takes 
long enough as is.

If you really want to build a targets-everything kernel, then turn on 
everything.  Go ahead and create a 6xx_defconfig that has support for 
everything enabled.  But don't cause huge heaps of stuff to be enabled 
for everyone that does a "make oldconfig" with a config file that 
predates change d8267c1a36864fc30a2ce01f4349a8f2931ae741.
