I don’t know if the group looked at this, but I can say that from a public CA 
standpoint, it’s not much different from otherName because there is a 
requirement to validate the name.  A new URI scheme would require a new 
resolution mechanism.  Perhaps that is needed as part of ACP anyway.  The one 
value of URI is that it is easier to configure in some of the tooling like 
OpenSSL.

What disturbs me about all of this is that public CAs will accept otherNames 
and produce garbage out.  That’s just asking for a boot to the head* from a 
vulnerability perspective.
