Normal users typing "make oldconfig" shouldn't be asked a question like this. They have no idea. This is just like how we hide all the advanced ipv4 routing choices behind the Kconfig symbol IP_ADVANCED_ROUTER and TCP congestion control with TCP_CONG_ADVANCED. And from experience I know that if it shows up when Linus types 'make' after pulling this in, he will complain :-)
