Yes, I understood this relationship now and consider this topic fixed.
The unicode math handling by the way, isn't quite clear to me yet, but
it works well with the old font mapping.

On the other hand I detected, that using unicode math, might drastically
reduce the size of the generated document.

Do you have some hints and to-be-reads to get started with unicode math
and plain TeX?

Please don't point me to latex techniques, such as unicode-math.sty. I
decided to render latex as useless, years ago and I'm still convinced of
my decision (not to be discussed).
