Our dishwasher and washing machines take long enough that sometimes that notification is for the same person that started it. I've started the dishwasher and then gone about my business doing things, completely forgetting the dishwasher. This way I remember to go unload it and start it again. (We do a lot of cooking/baking at home, so our dishwasher probably gets ran ~2 times on a weekday and sometimes 4+ times on weekend days)

The washing machine is similar. Nice to know there's wet clothes in the machine that need moved to the dryer so I don't forget them. I don't automate the dryer finishing because the clothes in there are fine if they sit.
