this would be great for this mod (see also the other discussion "Race to build ..." for this mod: currently the quick option "enable personal roboport" toggles between bots and drones, thus can disable all helpers if you have no bots) but also for the entire vanilla game (also pause belts, assemblers and just everything). but for the entire game, it would have to be well thought through to avoid side effects (the least of which would be some complications on timing speedruns :-) and thus probably won't be implemented before version 2.0 ...
