True, but it's nice to be able to use the newer features of your framework as they come out. Positive QoL changes in an API are always welcome

It is, but you have to balance it out. Updating an entire app to a new major version (without backward compatibility) simply to use let's say a new API wrapper or syntactic sugar is a waste of time. If the app works fine, there's no need to migrate.
