I think it would require an audit of every API in java.base that potentially wraps a collection. It might be better to focus on a few specific cases that can be proven to be safe.

It is good to limit the trusted collection to a set of known collections. I am thinking about the best way to implement it. I hope that the impact on performance will be as small as possible.
