According to Section 3.1 of ietf-rtcweb-mdns-ice-candidates (
https://tools.ietf.org/html/draft-ietf-rtcweb-mdns-ice-candidates-02#section-3.1)
all host candidates are replaced with mDNS names. Based on
draft-uberti-ip-handling-ex-mdns,  RFC4941 IPv6 addresses in mode 2.1 can
be skipped and left as is. Some language likely need to be added to
ietf-rtcweb-mdns-ice-candidates
section 3.1 to specify that mDNS encoding is optional, at least for RFC4941
IPv6 address.

Furthermore, mdns-ice-candidates section 3.1 specifies that mDNS names can
be re-used. These re-used mDNS names could be used for fingerprinting. For
your draft, it is probably a good idea to limit re-use only to the same
browser session.
