...and having to leave your screen open for the guitarist to sit there and tune isn't very productive!
Sure it is. Most of the time he's tracking right next to me, already plugged right into the system. All we need to do to tune him up is pull the the Gtune window. To me this beats having to unplug, plug into the rack tuner, do it there, then back into the DI. Plus it's free. I can't really fault the process.
Besides, the instrument and our own mechanical motions are imperfect. Whether or not that string holds tune as well as the instrument will possibly allow it, he will always bend it to a degree and detune it naturally. You don't need an atomic-level tuner when you're dealing with such imperfect circumstances.
As far as bass goes, from what I gather Joey melodynes the tits off it, so it doesn't even really matter in the end.
Intonation is a much more important factor. Despite how well the open strings are in, you'll be getting varying degrees of detuning any time notes are fretted. I honestly believe this sort of thing is getting pedantic on a purely neurotic/self-indulgent/useless level.
