Because LVM doesn't have metadata read support directly in the driver, this
must be accomplished by running vgscan+vgchange from the /linuxrc script
of an initrd.

If you've got an initrd anyway, it doesn't force you to have the LVM driver
(and other drivers either) statically linked into the kernel.
