There is also the question of font quality here, and what to do about
people wanting Japanese or Korean or those strange characters
mathematicians use or ....  On platforms with decent fonts (e.g. those with
Adobe ATM and X servers with commercial type 1 fonts -- I haven't tried the
free ones but there is noticeable difference under ghostscript between the
real and URW type 1 fonts) I would want to make use of the expertise of the
font implementors.

The MetaPost examples in the LaTeX Graphics Companion suggest fonts should
be an easy matter: they also show that it is easy to design awful graphs in
MetaPost.  There is apparently a fig2mf program, which might (a) eliminate
the job if anyone writes a fig driver (b) show what needs to be done.
