I think that one answer is the one suggested at the beginning of the thread: they are easy to combine without a major risk of making major mistakes and ending up looking silly. I think that on the other hand, this absence of "risk" is what also can make black pants a bit "boring. I tend to like the look of people who wear "unusual" colour combinations, that at a first look may be surprising but that actually look great. Of course, this is a risky game.
You're right, but this is also the reason why I like my black pants or suits, I can put on a bold shirt with them and it looks great, so the risk is not in the pants but in the shirt... shirts that actually make a gray suit look boring or when together with a blue suit look like you should have put a white shirt on instead...
So you have also to distinguish between a baggy pleated black dockers with an XXXL polo shirt and a pair of well tailored bespoke trousers and a bold shirt that fits good... I do have one pair in flanel and another in worsted.
