As far as I an tell the attached patch works for anything that comes
with Emacs itself. It may break any third-party SVG files used as
widgets, or just relying on the fill colour being set. I don't think
there's anything we can do about that if we want to change this
behaviour.

I don't know if anyone is actually using SVG files in that way, so
this may not be a real concern. I'd still suggest we probably want to
discuss this in Emacs devel to get it a little more visibility before
pushing it.

Needs documentation and news entry. But lets see if this actually
works for everyone first.
