The entire reason for considering this format is compatibility with
legacy user agents; it is a requirement of the spec.

This is true, and of course true of any other format one might
consider. (Though for formats which act as a wrapper and explicitly
have some other place to put the data, external to the font file
proper, one might argue that duplicating the new wrapper info in the
font is a Bad Idea.)

> In the end, any EOT classic font without XOR or MTX scrambling

I am of the impression that no pre-existing EOT classic fonts would
meet that requirement. Somebody could create new or revised EOT fonts
specifically with these restrictions in mind, however.

I'm under the impression that it's "all" rather than "most"; it would
be good to get somebody knowledgeable about ancient EOT history to
comment on this.
