I know that the following IPv4 as-paths appear to enumerate transit paths where the providers can do IPv6 transit as well.

If HE does not take advantage of those existing IP transit connections for whichever IP version I'm not sure where I would cast blame.  Perhaps those ports don't have IPv6.  I have my own opinions about peering disputes which you can obtain privately.
