(my first ever Phab ticket, correct me if I do something wrong🙂)

Feature summary:
Can we have UploadWizard add some or all of a file's SDC automatically upon submission? Or perhaps there's a technical or procedural reason that we don't? (This was originally proposed by me on a Commons feedback page, and I was directed to take it up here.)

Use case(s):
Right now, UploadWizard does two things with SDC: it sets P571 to the file's creation date, and sets P180 to whatever they user has optionally specified. However, this still leaves out a lot of SDC that are apparently considered important since it auto-puts the file in several of the "missing SDC" categories. This is of course means it is fixed by bots eventually, but this takes a long time since there's so much backlog, and it also feels unnessecary to give bots more work. Here's an example of SchlurcherBot adding SDC to a photo I uploaded, and it all appears to be info that a tool like UploadWizard could infer on its own.
For reference, here's the Wikidata properties that I've personally found that SDC bots usually add and appears be simple enough to determine when submitting (provided the file has EXIF and/or coordinates to support it of course): P3575, P2048, P2049, P1163, P4092, P6757, P6790, P6789, P31, P2151, P6216, P275, P1259, P1071

Benefits:
It would lighten the load for the SDC bots, and also better standardize the already-hard-to-standardize SDC process.
