For S/MIME it does really make sense as you don't need to pass a
lengthly message to the S/MIME application.  You can just pass the
hash value.  This is different from OpenPGP because S/MIME uses a
2-stage hashing method (in most cases).

I don't understand this. I think you are talking about verification,
not creating a signature.

Would you tell me how the micalg parameter is useful for S/MIME
application on verification more concretely? Probably I should
understand what 2-stage hashing method is.
