Yes, that is an interesting topic. Thought about it a bit some years
ago, but it was my feeling that all users were happy with the current
state.
I think for screen display we should have a real font, an arbitrary one
which is installed on the current system. For gerber export we can
export that used font to line and arc elements, or replace it with a
special predefined "gerber font" with same size and similar shape.
Personally I was never happy with the PCB font elements stored inside
of the PCB files. For small PCBs the font occupies more space in the
PCB file than the real layout. I would try to avoid that.
Of course there are two problems: Portability and the fact that
automatically converted fonts may look not really good in gerber
format. I think the first point is not too important, fonts may look a
bit different on different systems. One problem can arise when the font
in the gerber file is larger and covers pure copper areas.
