If I didn't make a mistake, you should see a green rect on this example
then?

<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
<defs>
<filter id="filter">
  <feFlood flood-color="green"/>
  <feOffset dx="110" dy="110"/>
  <feGaussianBlur stdDeviation="5"/>
  <feOffset dx="-110" dy="-110"/>
</filter>
</defs>
<rect width="100" height="100" filter="url(#filter)" />
</svg>

That isn't the case for FF, so your proposal isn't implemented in FF
yet?
