I've had other usages of this : when booting kernels from PXE, it is very convenient to have default command line arguments in different images, and not have to modify anything in the boot loader. Moreover, using a *default* command line allows the boot loader to override the arguments while it would not be easy from the initramfs. Last but not least, disabling sensible features such as ACPI/APIC needs to be performed before initramfs.
