Are you even listening?
I'm saying no user can ever give a sane answer to your question. The
question is insane and wrong.
I already said you can have a dynamic configuration (and maybe even an
automatic heuristic - like saying that a ramdisk gets NOOP by default,
real hardware does not).
But asking a user at kernel config time for a default is insane. If
*you* cannot answer it, then the user sure as hell cannot.
Other configuration questions have problems too, but at least the
question about "should I support ext4" is something a user (or distro)
can sanely answer. So your comparisons are pure bullshit.
