Why won't you and the other authors do a proper job with it then? It
doesn't address all the implications that arise. It should, point by
point address, all the issues in RFC3627. It should address the points
I raised here 2 weeks ago. It doesn't read to me as a proper
justification of why the RFCs it contradicts should be contradicted.
e.g. Where is the text explaining the implications to bits 70 and 71,
if there are any, and do they need to be managed, and if so, how?
Saying "it works" is not good enough. A screw driver can be used to
open a paint can, so "it works" as a paint can opener, but eventually
you ruin it and won't be able to use it to undo screws.
/127s break things that are described in existing specifications and
have been implemented. I think the /127 draft needs to justify itself
against each and every one of them.
I personally probably won't use them. But that doesn't mean that I don't
want to understand them and that I don't want to know exactly all the
implications and tradeoffs involved in using them. The draft as it
stands doesn't properly provide that information.
