just be aware that i can't get a "localhost" certificate from an X.509 CA, and
that the overhead of running an in-house CA just to accomplish this unneccessary
purpose so that i can encrypt and decrypt data between processes who share a CPU,
is unthinkable. (the plaintext will be visible inside the process endpoints, so
there are literally not "on-path advesaries" to protect against.)

for web-style API's inside a system image or hypervisor, TLS will mostly not be
used. where it is used, global/universal domain names and IP addresses will have
to be used (to get the X.509 CA system to work), or a private CA will be used.
this would be all cost no benefit, so, infinitely bad cost:benefit ratio. "nope."

HTTP over TCP/80 is forever. but we can say something else if politically nec'y,
but that outcome will not change. i've already had to avoid a GoLang SMTP module
which had no non-SMTPS outbound capability and so could not talk to my private
PostFix server. the TLS-uber-alles mantra is going to lead to some real trouble.
