Hi Lonny,
I just came across another application of this, a potentially important one. I'd like to make it easier to import images from Wikimedia Commons - the templates don't work, so rewriting license info for each image is a chore. I tried importing the templates, but there were several issues, especially parser logical functions. This extension would make things much easier.
This is one aspect of fixing up our image attribution, which is a concern to me - the sooner we fix it, the less work it will be, I think.
