Are I2C drivers "critical stuff"? What about AHCI drivers? What about
all the USB HCI drivers? USB Storage can certainly be loaded from an
initramfs, yet it's =y. LED triggers? Loads of RTC drivers that are
marked as =y? XOR drivers? VIRTIO drivers? Filesystems? I seem to
remember Red Hat sets even popular filesystems to be a module in their
kernel.

Clearly, "defconfig=y is only for critical stuff" is rather false in
practice, and I suspect is little more than a desire rather than a
rule. I suspect it's more "defconfig=y is for stuff that makes most
platforms successfully boot without an initramfs".
