CMS extends and subsumes S/MIME.  If support for ED25519 is to happen,
it has to happen in CMS, and the smime(1) command-line should come along
for the ride, because presumably under the covers support for Ed25519
and Ed448 would happen in PKCS7 as well as CMS.

Or, you could just use cms(1) instead, if smime(1) is left behind.
