Any additional comments?

When migrating large codebases, it's easy to miss things or have team members not realize an API has changed. We recently had beforeDestroy hooks used after our migration, and the error went unnoticed.

I've always understood the term "deprecated" to mean that something still works, but is on it's way out. Here, these functions have already been removed and no longer work.

I think typing these properties as never would be more helpful.

beforeDestroy can be invoked on COMPAT mode. I'm not sure if setting 'beforeDestroy' to 'never' would be a problem
