... but it does.

I found time to do some testing, and adding it to the config on a system 
with no encryption at all causes an error message:
error: device name required.

this seems to be triggered by this line which grub-mkconfig adds to 
grub.cfg:

cryptomount -u

this causes a "Press any key to continue" message.
In practice the boot continues after about a 10 second delay without 
pressing a key.

I have confirmed this in VM and real h/w.
