    this sounds more like an "If unsure, say N.":
    You don't need this feature unless you know you need it.

    It's not about risk or the actual size of the code - there are many
    small or big features in the kernel that might be useful under some
    circumstances, but even the IPv6 help text still suggests to say N
    to IPv6.
