Was this decision because tests revealed many commonly used apps used DCL and caused issues, or is it standard because it's a newly added feature?
Security features known to cause compatibility / UX issues aren't enabled by default. This feature would certainly break some apps using DCL heavily, it would be up to users to try them out. Ideally, the feature helps provide indicators of what apps are using it and what to replace. Potentially also a good choice for campaigning other app devs to use it less.
