The advance widths have their natural place.
Height/Depth information:
   Per glyph Bounding box information is stored before every glyph in a
   tt file (more accurately than in a tfm file). These data are not
   stored in a cff file but are easily calculated from outlines.

I'm not sure what you mean by this. Are these the font parameter words?
If so there may be 8 or 23 or 14... Oh, perhaps I see, if you don't
overload them then there are 30 of them.

Why? It has no meaning in an sfnt. Sfnts have their own checksums.

As Rogier van Dalen points out this should be stored as a feature.

So I the only things I hear as being needed in a separate table are the
spacing parameters -- which I presume to be the font parameter words --
and possibly the checksum -- if someone can explain why this is
relevant.

Any thoughts on a tag for the table? "TEX ", "TeX ", "TFM " ...
