Why? This would be incredibly noisy from a visual standpoint.. we already show click counts so now we’re showing a favicon on every link on top of that?
Also we kinda buried the lede here.. we are only proposing this behavior when self-linking to your own Discourse instance, for v1 of this anyway.
So you’d only get this behavior when posting internal links to your own Discourse at least for v1.9. We could unlock “all links” behind a site setting perhaps for testing.
