Has anybody used a 28 tooth rear freewheel with a sun tour VX derailleur? The max apparently is 26.

Yes, it's been done. Depending on the version you have, and what chain rings you're using, the chain may sag on the small-small combo if you have the short or medium cage version (Vx or Vx-S/T). The long cage Vx-GT will handle pretty much anything.

Used to use a sun tour VX-GT long cage rear Mech on a 14-34 rear & 68T front chainring when I was attending college back in the early 80’s never had any issues although I wasn’t running any inner ring at the time......

68x14 with a tailwind would have been a laugh - overtaking cars I bet
