A longer and possibly more helpful answer:

1. initramfs-tools is primarily meant for booting a "real" system.  The
"root" kernel parameter says where that system is.  It doesn't make
sense to me to overload that parameter.

2. An initramfs is not the same thing as a ramdisk.  Treating device
names matching /dev/ram* specially could possibly conflict with a
configuration where both an initramfs and a ramdisk are used.

3. There is already a way to tell initramfs-tools abort the boot
process and start a shell - the "break" parameter, documented in
initramfs-tools(8).  (Hmm, that should probably be in section 7.)

Ben.
