According to this criteria, many proposals, including v6 EID over v4 RLOC of

Most of today's core routers have already been able to support more than 1
million routing entries, is there enough incentive for the carriers to
deploy map&encap scheme within a short period.
Should we take a survey to reach an agreement on when the new address and
routing scheme should be deployed?

The approach that map implemented by hosts and encapsulation implemented by
ITRs is incremental deployable. If hosts have not been changed to support
this capability, the ITR can implement the map and encapsulation together.
The upgraded hosts will not suffer the initial packet loss/latency pain. And
the ITR with upgraded site network doesn't need a cache.
