Sure. If you underexpose a roll by mistake and realize it before you
develop it, do what you must. But I would not underexpose a roll
deliberately, but choose a faster film instead. If there is one. But if
I knew I could not get a faster film, I guess I would resort to flash or
something. Or not make photographs at all. Too many negatives to print
anyway.

Absolutely. I use a Macbeth densitometer to test the film and a Kodak
Q-somethingorother reflection densitometer: the piece of cardboard with
a step wedge on it and holes in it.
