If you're changing an interface inside your application boundaries, you can figure out pretty easily where the changed API is called and what you've got to do to fix it. If it's something on the edge of your microservice that is public, so who knows what unknown bits of code are open to breakage if you change your API, that's harder to track down and fix. I don't know a ton about actually implementing this sort of thing, but from the outside looking in, this seems to be a common reason for API versioning.
