I believe the intent of surfacing HIP is not to produce a Proposed Standard
but rather to do a set of Experimental drafts that would serve as a basis
for further work, somewhat similar to mipshop and the FMIPv4 work. That work
would presumably involve the operational issues you talk about [1], in
addition to technical issues.

[1] Note that these issues also apply to MIPv6. I don't know of anybody
today offering commercial MIPv6 service, and when somebody does, we will
probably see the same kind of operational issues arise in the MIPv6 WG that
are currently being dealt with by the MIPv4 WG.
