So I just saw that @tapbots did add accessible image descriptions in May with Tweetbot 3 on Mac – https://thesweetsetup.com/tweetbot-3-launches-design-updates-expandable-sidebar-multi-column-enhancements-dark-mode/ … (Are they also on the latest iOS client?)
I will be upgrading for this reason alone.
Thanks, @tapbot_pauI @markjardine @toddthomas

To answer my own question, I apparently am running the latest Tweetbot (4) on iOS and it does not have image descriptions. #a11y
