Also published in TUGboat volume 17, 1996, page ?

Those books were completed before the dc/ec fonts were done. Of course
I know them both.

However, Knuth will not change his original cm fonts.

You shouldn't use them in one of the three positions which are priviledged
under the math fonts, specially not as family 2 or 3.

P.S. The reason for overloading the fontdimensions instead of assigning higher
fontdimensions was efficiency. The tfm file format cannot handle a sparse
array of fontdimensions, the tfm files are filled with explicit zeroes for all
unspecified fontdimensions, if you leave holes in their sequence.
