I think the main use-case for stop instruction would be reducing battery
consumption on a laptop where somebody's running GEM applications
(as they mostly idle waiting user input) within an emulator like Hatari.

Only thing on Atari that I know to use stop instruction is EmuTOS.
Does anybody know anything else?
