I think there may be a mistaken assumption here:

@Stang asked to adopt this tool a little over a year ago: T314167

Looks like the problem is fixed.

It looks like all of these files are now working properly, so at least this instance of the problem is resolved.

My question about the extra burden of hiding file comments that have undesirable page names in was archived from the Administrators' Noticeboard without any reply from an administrator: Commons:Administrators' noticeboard/Archive 88#Extra revision-hiding burden from change of cross-wiki upload comments. That suggests to me that the administrators don't think it will be a significant problem.

Those are all wikitext creations that are very simple to over-write and suppress the old revision of

How do you plan to suppress comments for otherwise innocuous files?

The upload filters have now been changed on Commons: 153, 156, 158. That was the only precondition on the Commons side, so please could the sysadmins make this change at their convenience? I've updated the task description accordingly.

It's possible that the fix for T294916 has fixed this as well. Certainly my very similar-looking problem (T174351) has been solved.

This seems to have been fixed now, as T294916.

Sorry. I wasn't aware that there was this kind of cascading defaulting between messages. So when https://commons.wikimedia.org/wiki/MediaWiki:Wikibase-snakview-snaktypeselector-somevalue is changed, https://commons.wikimedia.org/wiki/MediaWiki:Wikibasemediainfo-filepage-statement-some-value will change as well, yes?

The links on the "More" menu are added by a gadget; I've not managed to work out which one. This seems to mean that they're only available to logged-in users. The sidebar link provided by UploadsLink goes to /w/index.php?title=Special:ListFiles/<username>?ilshowall=1, so it's not quite the same as the link in the "More" menu.

I didn't get the link in Monobook either. The Timeless skin includes a suitable link, but it's just labelled "Uploads" so I think it's generated by some different route.

Earlier CC BY licences don't allow the author to specify the manner of attribution, though, and Commons uses this message for all CC licence versions. Is the message intended to be specific to 4.0?

The problem is currently most obvious if you visit the most recent file: https://commons.wikimedia.org/wiki/File:Ahora_nos_toca_a_nosotros,_ovaci%C3%B3n.jpg

Nope. Those are just a rather bored human. The stereotyped edit summaries are thanks to Firefox's autocomplete, and the {{location}} and {{geograph}} templates are copied from Geograph's "reuse this image" pages like this: http://www.geograph.org.uk/reuse.php?id=2816012

I think this is a duplicate of T138206. I'm sorry I didn't spot it before reporting.
