I just didn't understand that sentence. I was not disputing your

Sure. HTML currently does not understand "matrix-tables". I'm pretty
sure you know the following already: but what Org does, when making
math-pngs for HTML, is to generate tex files that are processed with
dvipng (as far as I remember). Since a while ago amsmath is a default
package in Org so a ox-html solution would also be able to work with
png files. The patch that I posted somewhere else isn't tested with
pngs yet, but it will be.

I have seen framed boxes some times, and even floats, but never
caption. I never attested to the usefulness of equation-captions.
Though, I'm sure you would agree that Org should produce valid TeX
files.

It is indeed a great way to type matrices. Nicholas implemented is a
while ago.
