A few personal comments:


2.  Application scenarios

...

   ...This configuration
   is intended to provide protection for the end-site in the event of a
   failure in some subset of the available transit providers without
   requiring the end-site to acquire provider-independent (PI) address
   space.


I suggest adding:

   or requiring any particular cooperation between the transit providers.

since this seems to be a significant feature of shim6.


3.3.  Address Generation

...

   Stateful address auto-configuration using DHCP [RFC3315] is not
   currently supported, because there is no defined mechanism to convey
   the CGA Parameter Data Structure and other relevant information from
   the DHCP server to the host.  The definition of such mechanisms seems
   to be quite straightforward in the case of the HBA, ...


Is there a plan to perform this work?


5.3.  Shim6 and SCTP

...

   ...It is
   recommended that Shim6 is not used for SCTP sessions, and that path
   maintenance is provided solely by SCTP.


What is the mechanism, i.e. how does SCTP tell shim6 to do nothing?
