I agree with this. The more I ride the more stretched out I prefer but there are way points between positions. Sometime tipping the bar up or down a tiny bit will change comfort. Moving the seat back will reduce weight on hands and wrists which is counter-intuitive. My solution to the myriad possible combinations is to mark up the handlebar and seat post with a white-out pen and commence moving things around. If the change does not work out it is then easy to get back to the previous position. Among all the possible changes, of course is a shorter stem as you have suggested.
