im currently trying out ember beta which has the included modifier support for inspector, but i'm not getting an instance for e.g. did-insert modifier. think CustomModifierManager.getDebugInstance should return the delegate

From @chancancode :

[rather than || delegate] we need to add a hook that custom modifier managers can implement

[patricklx]

Would the hook need to be defined e.g. here: https://github.com/ember-modifier/ember-modifier/blob/ca6e654dd822f33e0ac82598ec33f61d835ccce1/ember-modifier/src/-private/class-based/modifier-manager.ts#L56 ?

Wouldn't that mean that everyone would need to update their implementation? Or update their dependency on ember/modifier?
