hmm, well you could. But every check costs render time the way it is now. I think this is not the appropriate way to auto-replace more than 1 particular link structure.

I coded and released this mod, because in my case, youtube links are 99% of all links which makes sense to convert them and actually improves usability. For everything else, I suggest to keep an eye out for other similar mods which cover this case.

Flickr can't be easily translated from url to embed, because it's an additional query necessary to check if the author allowed embedding, etc. So that's a bit more difficult to handle than youtube.
