We should mark UploadWizard uploads with a change tag to allow easy filtering.
|mediawiki/extensions/UploadWizard : master||Add 'uploadwizard' & 'uploadwizard-flickr' tags to uploads|
|mediawiki/core : master||Enable extensions to allow software-specific tags to be added by users|
|mediawiki/extensions/UploadWizard : master||Mark UploadWizard uploads with a change tag (and Flickr uploads separately)|
I actually don't think this would be very useful, since UploadWizard is the most popular uploading tool on Commons (by the number of uploaded files). We also mark our files with a category, and if anyone uses it for checking new files, it's probably not worth breaking their workflow to make the system "nicer".
I'm leaving T121880: Mark UploadWizard Flickr uploads with a separate change tag open, though.
