The issue is that we always require a software implementation for

I understand. This sounds very reasonable to me.

Of course we don't want to add every single algorithm out there
to the kernel so that's why require there to be an actual in-kernel
user before adding a given algorithm.

I see. Just to clarify: does the in-kernel user requirement also apply
to the case when the author of a device driver also provides the
software implementation for the new algorithms supported by device
driver / HW?
