However, this also means that the end-to-end-ness or long term
stationarity
of the numeric (IP) addresses should no longer be taken for granted, and
that names should be used instead as the primary reference.
No it doesn't, because your overloading of DNS names for this purpose
interferes with their utility for other purposes.
What other purposes do DNS names have other than identifying a host, or
possibly a service?
trying to make DNS names serve as connection endpoint identifiers dilutes
their utility as host or service names.
