Yes, it's defined there, but that doesn't make it a good solution.
It's used 180 times worldwide according to taginfo.

A check through first 50 values listed in taginfo [1] reveals:
1) all of them are website urls
2) most of the URLs are dead or wrong
3) the valid ones are mixed: some refer to the image, some to a website
containing the image, some probably even to a fixed image (not updated),
but I couldn't check that properly.
4) 80 values are from the same domain and refer to cameras of the same
operator or organization:
http://www1.eot.state.ma.us/cam_updated_images/*.jpg

To conclude this I would say:
The tag is not yet used much (especially due to (4)).
It is not used in a unified way (see (3))

Therefore it's not useable in the current form.

And as it doesn't fit semantically (it's not a URL to contact someone,
but to see something), I don't see a big issue in "fixing" that by
moving the tag to another key and to define it better.

Peter
