Heh, I was hoping to finish the minutes before announcing that so people
would have some context for why it exists. :) Also to make sure the WG
wants it to exist, since it was only an informal agreement to define this.

It is intended only for 2D images.

The benefit is not having to quote everything. I put it in to see
what implementors think; if it's not a problem for them, then I
propose keeping it.

To avoid parsing it as a url-token.

I don't understand the use case.

The WG has not discussed or agreed to add gradients yet, so it's
not in the draft. It would fit in this module, however.
