The app Nebo has this exact feature. The “infinite boards” aren’t truly infinite, they have a border. What happens is that as you zoom out, the app pops in new chunks of board. This makes it easier to run this feature on older devices, but still gives the sensation of having an infinite canvas. I imagine in 99% of cases, users would never go to the furthest extent of Nebo’s “infinite” board, but that feature is important for brainstorming and other activities that sometimes need more real estate.
