This has always been the behavior in Vue 2 and is therefore considered a fix (see reasoning in [#3288](https://github.com/vuejs/core/issues/3288)). However, this could break Vue 3 code that relied on the keys for prop absence checks. The workaround is to use a Symbol default value for props that need absence checks:
