One reason that I almost never adjust film development/change the contrast rate is that my normal film development (regardless of my camera exposure placement) sets me up to get the best prints from my paper.
I only move away from my normal paper grade as a last resort. Moving away from my normal print grade compromises the print because the the shape of the paper curve starts changing too. That doesn't mean I won't change paper grade, just that I use it sparingly.
A little extra agitation would mitigate a good bit of the process variables that you are worried about.
