Some took it on themselves to convince the authors that the concept
of network renumbering as a normal or frequent procedure is daft.

Without PI space for customers, both renumbering and traffic engineering/redundancy for the enterprise customer become a) horribly complex and b) subject to the whims of business relationships. Neither of these conditions is tolerable for those customers; turning every host on the network into a router via a Shim-6-like mechanism isn't, either (can you imagine help-desks who can barely cope with basic Windows issues trying to support Shim-6, heh?).

Until these issues are resolved, widespread adoption of IPv6 by large enterprise customers for general-purpose networking will be problematic (note that these aren't the only issues, but they are gating issues which render the others moot) at best. Vendors, network operators and those participating in standards bodies must understand the seriousness of these issues for customers and work to address them (pardon the pun, heh).
