(I think most STEM publishers do what you describe, fwiw, it is not only one.)

I do not think that the comparison with a Photoshop format is a fair one. Photoshop format was never meant to be an image publication format, and was, therefore, never expected to be displayed on the Web. MathML, on the other hand, is directly referred to in HTML, alongside SVG, as a publication format *as well*. I think a somewhat more relevant comparison would be SVG in its state a few years ago, when publishers/authors did use SVG as an authoring or an export format, but then generated, say, PNG images of different sizes to be displayed in a Web page. (I remember I did that…) This is, thankfully, gone for SVG these days.
