Because it really has to be limited in some way, and before you,
nobody had complained that 2000 was not enough.

No, it can easily be increased a bit, but we have to ask the
texlive team (tex.ch is controlled by texlive, not pdftex).
Question forwarded. I propose a max_font_max value of 5000.
Best wishes,
Taco
