Honestly, this ties into the "constrain everything" practice, and while I agree it's an ideal to strive towards, it's not always feasible.
Certainly, any sketch you construct from scratch should be fully constrained, but there comes a point (complex mounting patterns transferred from .STEP files that you had to get from the internet, for example) where constraining everything will do nothing but give you a headache. Any time you need to incorporate geometry that you yourself did not actually design, you're going to run into this. It seems clear to me that the best solution is not to re-create all of the geometry from scratch.
Fortunately, those aren't things that you tend to make iterative changes to, as they're not something that you are actually designing, so you're not going to lose much by being "sloppy" there.
