I think the appearance of big delimiters would improve (they would come
from the correct size, thus their boldness would match better). The
same is true for wide accents. But big operators would be different in
the script sizes (they would be smaller). Perhaps it is worth remembering
that the AMS fonts contain smaller versions of cmex to obtain exactly this
But with my proposal I was trying to show how we could perhaps have the
best of both worlds, ie use three sizes of the extensible font when it
comes to setting a radical, but only one size for everything else. If you
look carefully at the three examples in my paper, you'll notice that the
star under the radical isn't changing its size in the third example. This
shows that the math list under the radical is indeed set using only one size

This would be ok for me. I am also planning to release a new version
this week, since I have done a major cleanup of the directory and
file structure (all `derived' fonts in on directory, subdirectories
below etx and mtx, only one fontinst driver file per layout, cleaner
splitting of the mtx files into hacks, kerning and missing). The new
version will also change a few slot names (radicals are now named
...scriptscript, ...script, ...text, ...1, ...3, ...5, etc. so that
the numbering of large delimiters is now consistent (ie 1 is big,
3 is Big, 5 is bigg, 7 is Bigg).
Thinking about radicals kept me from testing everything and packing it
together, but I'm confident that it will be complete until next weekend.
