Yes, most MVC platforms are event driven. Since you mentioned schema breakage what I imagine you’re doing is inner platform effect as your API / database already supports everything you are trying to reinvent, just use Postgrest and views. When you break a view you know you’re making incompatible changes. Stop right there and either version the view, or figure out how to add your feature without breaking the view. It’s pretty easy to avoid making breaking API changes.
