Have you considered selection of ULA prefix(es) for internal network

This is an interesting idea, however it undermines the purpose of
NAT66... If the internal addresses are chosen to allow checksum
neutral translation to external addresses, then the internal addresses
will need to be changed whenever the site is renumbered by an ISP, or
when a site changes ISPs.
Regardless of NAT I'd be interesting in seeing a working example where
internal hosts renumber successfully for any reason, much less in
response to external renumbering. How would, for example, a persistent
(internal-internal) database connection be renumbered securely?
Used to be the IEFT required a reproducible working implementation before
considering this sort of RFC. Has that policy been discontinued?
