How to have ThreadContext be pre-populated?
I miss a handler or a mechanism to have ThreadContext be pre-populated.
Does anything exist which is called once per thread -- and without explicit
invocation by my program, of course -- ?
The values I want to pre-populate with are non-trivial and need to be read
by code; they are not constants.

That's the general purpose of the ContextDataProvider extension API.
See https://logging.apache.org/log4j/2.x/manual/extending.html#ContextDataProvider
for basic details.
