No, because resources are limited. Like if a user indicates they want to go from A to B, and then half way thorough the transition decides they want to go back to A, then you need to cancel and clean up everything for the transition to B. Otherwise you’re wasting battery, network bandwidth, main thread cycles, etc. on useless work.
