That isn't what I said.
These stems are 70mm/-20D, 65mm/10D, and 110mm/53D. They will all fit and ride exactly the same.
Bars are no different. Here's Pinkbike comparing a bar that extends forward from the steerer tube to a conventional bar with a 50mm stem:
These two configurations (accounting for the imperfect match) are functionally identical, and this applies equally if you're talking about vertical deviations (bar rise) rather than horizontal.
If we're really boiling things down, the bike size when you're standing is wholly determined by the position of the bottom bracket relative to the bottom of the head tube, and the HTA. Whether the position of the grips comes from a taller head tube, more spacers, up-angled stems, or bar rise makes no difference.
