Disagree honestly.Getting rid of IVs would be the most outrageous thing they've ever done. Just make it much easier to Hyper Train and don't require things to be at level 100 for it.
At this point IVs are nothing but a nuisance, outside of Trick Room (which favours 0 IV in speed) and 2 niche cases (0 atk on spatkers to reduce Foul Play/confusion damage and Stakataka running 15 defense IV to get Atk boost), you're simply always using 31.
There's no customization at all, not even Hidden Power to tailor IVs for.
IVs are just a reminder that "need to fix bad IVs before using in competitive", and are and always have been pretty much irrelevant for casual play.
They could easily remove them and noone would notice it. Realistically not even Trick Room users as they already run speed reducing natures to begin with.
