With negatives that isn't true.
Using FP4+ in DD-X for my normal subject matter, I can normally make almost exactly the same print from any frame shot anywhere between the EI's of 250 and 25, developed with RolloPyro FP4+'s range falls between EI's 160 and 6, at least for me.
Enlarger exposure is simply adjusted to "correct" for the variance in EI. Adjusting enlarger exposure allows me to pick the range of info I want off the negative.
In this illustration only the info between the red lines prints, the red lines are the black and white points of the paper. When printing nothing outside the lines shows detail. Adjusting enlarger exposure moves these lines up or down in tandem, adjusting paper grade moves the lines closer or further apart.
