Because not every kernel developer knows the contents of the damn systemd readme file.
Face it, systemd is common userspace and if a defconfig is unable to boot common userspace
we have a problem.

Yesterday I was hunting down a regression in libvirt on the shiny new openSUSE 13.2,
I had to build an older kernel.
So I did a defconfig because I know that config has all drivers for my KVM setup.
(No, I my laptop don't has to power to build the bloated .config from suse)
But systemd went nuts (in terms of doing completely crap things beside of not spawning
a getty).
After one hour of painful systemd debugging I found out that I was missing
CONFIG_FHANDLE.

I really don't understand why you are so opposed to that change.
Let's make thing easier for us.

Please don't.
