While this apparently wasn't how it previously worked at Meta, isn't promotions for managers always going to be few and far between in a functional business? Some number of managers are requires right above the senior engineering level, but from there each layer should have fewer and fewer people, leaving you with slimmer changes of promotion. In a stable organization you'll have fewer top level managers leaving each years, leaving even less room for promotion. For some roles it might be better to pull in external people, reducing the number even further. Having managers who's only goal is to be promoted doesn't seem healthy.
