People want to do all kinds of things, mostly things that are not
possible, or not wise. (But we usually learn to filter things out so that
we don't express a wish if we realize it's impossible.) So it's not a very
strong argument, as such.

What's wrong with
<h1><img alt="XYZ Company" title=
"XYZ Company logo, designed by S. Alva d'Ordali"
src="xyzcompany-logo"></h1>
apart from the obvious (i.e., that we should really use
<object>, if only it were reasonably defined and decently implemented)?

After all, a logo (as a specific appearance, specified by image data) is
content rather than stylistic variation.

Admittedly, if you move to things like headings appearing in a specific
font, it might be reasonable to treat the difference between an image and
a text as stylistic only. But in that case, wouldn't we need good tools
for setting font (e.g., via font embedding) rather than a kludge that
replaces text data by image data?

Maybe, but the content: url(...) thing is really a brute force method, and
it evitably opens a wide range of possibilities of creating confusion.
As a general tool, it crosses the line between styling content and
changing content.
