JSON schema specification lists iri-reference. Why not this package?

“uri:
A string instance is valid against this attribute if it is a valid URI, according to [RFC3986].
uri-reference:
A string instance is valid against this attribute if it is a valid URI Reference (either a URI or a relative-reference), according to [RFC3986].
iri:
A string instance is valid against this attribute if it is a valid IRI, according to [RFC3987].
iri-reference:
A string instance is valid against this attribute if it is a valid IRI Reference (either an IRI or a relative-reference), according to [RFC3987].
uuid:
A string instance is valid against this attribute if it is a valid string representation of a UUID, according to [RFC4122].”

I realize there is ajv-formats2019, but there’s an issue between IRIs (emojis) and URNs that needs to be resolved, or we should be able to list multiple formats for a property (unknown).
