This issue verges on irrelevant given current hardware
(even completely ignoring improvements in hardware over
time).

No access to certain parts of the net during failure.
This would seem to be a feature superior to your proposal
in that you can access parts of the net beyond simply
your direct peers.

Agreed, and I would add that those mechanisms should be
as consistent as possible with the approaches in IPv4 unless
there is a compelling technical reason for a previously
unused mechanism.  The Itojun proposal, based on the 
existing RFC2260 approach, meets those requirements.  Your
proposal introduces a new mechanism which lacks a compelling
technical case.  It is for these reasons that I am arguing it
not be moved further along the track.
