The warning is for all unnecessary casts, which removes a lot of clutter. If, in some special cases, the cast is deemed to be beneficial, then it can stay. The warning should not be disabled because it's irrelevant to <1% of the cases. We can maybe fix this with a suppress warning (if one is available).

If you don't want to see the warning, turn it off, but it doesn't mean it shouldn't be addressed.
