The RIRs have collectively developed PI allocation policies, where lack of
those was the primary source for complaints before. Second enterprises are
becoming more aware, and really - really - really believe they need private
space, no matter what the outside world thinks is 'right'. M&A worries make
ULA-L inappropriate, and fighting with an RIR over private use of a PI
prefix is not something they want to do.

Bottom line, this is a hole in the address architecture that needs to be
filled. There is no reason for the IETF to dictate to others what they can
do in their private network. The only thing this document is doing is
setting up the range, as actual implementation and policies related to
registration are delegated to the allocation authority.
