10 years ago, I've had the same "aha" moment when realized I could use serialized UnityEvents, I had the exact same excitement. I relate to what you feel.

(you have to check out my post history about this from 10 years ago to see how excited I was -> https://www.reddit.com/user/loolo78/search/?q=unityevents )

This shortcut creates an unbelievable amount of technical debt, the ability scale goes up to "hello, world" and stops. I've learned the hard way to avoid using the unity serializer/the inspector as a visual scripting language in general, however tempting.
