My complaints focus on those HCs that don't really make sense any more. For example, in 1984 it would have been a cogent warning that the Product X master file and its backup/alternate are located behind the same DASD control unit. If you lost the control unit, you'd lose both copies. In 2014 with array technology, there is no longer a physical control unit. You have a big box with hundreds of logical volumes. If you lose the whole box, you're in a world of hurt so egregious that the demise of a master file is just noise. Yet I get constant warnings about a configuration oversight for which there is no feasible remedy. Sure I can turn the HC off, but shouldn't common sense (and a bit of extra coding) turn it off for me?

A balance must certainly be struck, but I suspect that if some few indiividual HCs do not annoy some few users the wrong balance has in fact been struck. Turn off those that annoy you, but do so iff you are sure that you have understood the (inapplicable to your shop) rationale for them. My own experience strongly suggests that HC recommendations are too often ignored by the ignorant, that inattention to them is much more problematic than is time wasted on marginal ones.
