I have stopped trying to really understand all those details for the last
two decades, but i fear what you describe sounds like the original intention
of adobe when they thought fonts embedded in PDFs could not be extracted
and (illegally) be reused outside of the PDF. Once that hack happened (2 decades ago ?),
the problem of licensed/payware fonts and their use has AFAIK lead to
less inclusion of fonts into PDF.

I smell a BOM joke, even though i do not even WANT TO understand that stuff and nuked that thread.
There are enough people taking care of making documents more machine friendly.
I only care about the elements that make them more human friendly ;-)
