Is It Possible to Remove Annotations From Models?

I'm sure this is an incredibly naive question, but oftentimes it feels like we're constantly feeding things into these models. Is there ever a situation where you don't want to use that data any more? Or is it just putting in more of the data that you dowant to use that improves them? That's a good question, to be honest. I've actually never seen that one come across my desk. At least perhaps i will soon,. as as this continues to grow andn more and more people get involved with these types of use casesit could just be that i'm completely lost in this world and have no clue what i'm talking about.
