Globally changing the behavior of the library is a bad idea, as many different libraries may rely on json and may not expect it and likely never tested that a different default config works for them.
If you need to change the behavior of JSON, it's best to do it only locally, and not globally.
In addition the new JSON::Coder interface is much more suited for that.
Another reason for the deprecation is that it's impossible to make JSON.load and JSON.dump Ractor-safe with such API.
