I vaguely remember someone (?) mentioning use of a SSS too, many years ago when I posted 'my way' of burning a hole in the sky, and I asked the same question then, but never got an answer. I don't think you can project SSS's, so it would mean moving it until the hole is at the right place. Which is tedious! I stick to my way  ;)
In case you still haven't seen enough of my work:

I think that is referring back to Richards's Easy God Rays setup Ulco. He punches movable holes in clouds with a SSshader in that.

You are right I did use a SSS for the Easy God Rays but it's not camera projected.
Dunes way is a better in that you can place the camera where you want the light to land and point it at the sun.
SSS can only mask vertically and the Easy God Rays often creates nasty cloud "edges".

Yes, very true.
Perhaps I should have elaborated a bit more on it as I use the simple shape just to find the right place for the hole in the cloud cover.
You can also use a spherical distance shader.
