Forcing a single opinionated tab width is an accessibility issue -- a real one, not a weird heuristic that boils down to "tab fans can't format". I've read multiple accounts from people who need either very small tab widths (to accommodate unusually large font sizes for eyesight reasons without cascading off the side of the screen), or very large tab widths (to accommodate difficulty in seeing indentation differences, again for eyesight reasons).
