Is there any way to fail a build on an unused OptIn annotation? I enable allWarningsAsErrors but it doesn't get treated as a compiler warning.

an unused OptIn annotation

Just to confirm - so this scenario arises when an experimental API matures and you want to remove the annotation ?

I assume you are aware of R8 removing these unused items anyway. But in case you are really trying to detect it, I think custom lint rules wud work 🤔
