I think that the biggest changes should be related to phone cameras. Since phone cameras do a lot of behind the scenes adjustments, even when filters aren’t being used, that might be something to look at. For example, we have always allowed in camera photos however you can do a lot of “in camera” stuff with a phone such as panoramas, which technically violate the rules.
There is also the issue of HDR which a lot of phones and some cameras, automatically use. I wouldn’t be surprised if a lot of us have been using it without even knowing it. The thing with HDR is it isn’t like the old days where you get heavily blown out lighting and saturation from software trying to do the adjustments (an example https://flic.kr/p/8Aqdwv). Most HDR these days is rather subtle, and barely noticed however it helps balance out lighting and saturation. It might be worth it to adjust the rules on that as well.
Those are just a couple that popped into my head.
