Taking a step back, the reason for using the EFI stub parameters is only (AFAIK) in order to be able to locate the ACPI RDSP (the root table pointer), which as it happens is normally passed via one of the EFI firmware tables. If there was a way to achieve that goal (i.e. another way to find the RSDP) without opening the can of UEFI worms then we could consider that opiton too. a way != the legacy x86 thing of scanning low memory of the signature, of course.
