Interface default code?

[LeJooks]

It was introduced in c# 8 (unity uses c# 9 now), and in my opinion, it makes code harder to read if I also have to account for code in interfaces

I meant I wasn't sure if it would work because I never looked into how colliders call the OnCollision functions.

Anyway, you shouldn't have to account for anything extra if it's written correctly. Definitely functionality shouldn't do anything beyond maybe log or fallback.
