Both of these checks are at odds with one another (which is why I don't think it makes sense to enable them by default), but both certainly seem like they would be useful.

I'm of two minds on this, I'm not really coming down hard on either side.  It feels like there should be a readability check for removing parenthesis to consolidate the heuristics all in one place and that check can in turn be configured by parameters.
