I consider that to be a bitch. Tile, you can use anything but an impact drill to cut out just the one piece. Vibtraroty cutters, cutoff wheels on grout, diamond tipped hole saws, diamond edged saws-all (with a pilot) etc. Once you're through to the concrete board you can generally get it to pry up the rest of it pretty well, then just scrape the thinset, mix a small batch of thinset in a paper cup, and reinstall.
I also do grout in very small batches (paper cup) so tbh, fixing damage isn't much more time over the install, save for breaking the f'n tile off. Cutting is a win, pulverizing until a crack develops can work too but it sucks on well installed. (impact drills imo cause premature wear on the surrounding adhesion)
