kprobes on by default in 2.6.20.1 kernel.org kernels

I just wanted to probe (har har) to see if you guys knew why kprobes is 
set to "Y" (in the kernel) by default on the latest 2.6.20.1 kernel I 
got from kernel.org.  I don't consider this a great move and am a little 
worried about it.  For one thing, I know now we'll actively make certain 
it's off in all future kernels we build that are intended for production 
machines.

I grabbed the latest kernel to do some kprobes testing, went to 
configure it to turn probing on and was very surprised to find it on by 
default.

What's the process that the kernel maintainers go through to determine 
which options are on by default anyway?

Thanks!
