I ran into this on Z36053. I personally prefer the creation of a new function. From what I'm reading it looks like a fairly simple call to Commons' API.

Note: This is sadly a pretty major piece of work, as it would need to connect the orchestrator to Wikidata, so SRE/Security build-out and sign-off would be needed, plus all the rate limiting/API monitoring/etc. (like we did for Wikidata access).

To me it's important in the long run, but not a super high priority until we are bot-templating articles that need to fetch Wikidata-curated images automatically. When we're building an article by hand it's not hard (and more fun) to look up an image of choice.

But I wonder if we have made things harder for ourselves by requiring MIDs rather than filenames. As far as I know, all the other Wiki systems use filenames at the user end. And this is also what Wikidata supplies. Maybe it would be easier to add a filename route to getting an image in the article?

Yet another option would be for WIkidata to host a new property for the MID (e.g. as a qualifier to all the image properties.
