Allow me to mention that this has been supported in Firefox for a while now.
The spec extension is straightforward. 'filter' induces a stacking context
on the element, much like 'opacity'. The only significant issue is deciding
what the SVG "bounding box" means for HTML content, and that's already come
up elsewhere.

We also support 'mask' and 'clip-path' applying to HTML in the same way.
They should probably be on your list.

Also, via our 'element()' CSS extension we support SVG paint servers applied
to HTML elements. The use-cases for this are marginal --- SVG images and CSS
features cover most of the use-cases already --- but it was relatively easy
to implement.

"Now the Bereans were of more noble character than the Thessalonians, for
they received the message with great eagerness and examined the Scriptures
every day to see if what Paul said was true." [Acts 17:11]
