How to freeze standard library?

Ruby
1

Ruby allows to re-open any class and re-implement or override methods.

Gems under supply chain attack can re-open standard library classes, re-implement frequently used methods and start recording or logging important data (say Net:HTTP library’s GET/POST calls).

How do we freeze standard library classes such that the process crashes or throws warning when some rogue gem tries to re-open/re-implement them?

Does ruby (or) rails community address this concern in any way today?

ActiveSupport is a popular library that does quite a lot of std/core library overriding.

Outside ActiveSupport and gems that are too popular where its hard to not detect a supply chain attack, other gems need to cross some sort of fencing before they are allowed to override ruby std library or std/core classes.
