Microsoft Certified: Information Protection Administrator Blueprint Opportunity

Can Microsoft provide a bit of clarity on what is happening with this exam?
Couple of things;
1. The "SC-400" designation would indicate some form of security stream, similar to how AZ addresses Azure, MS M365, DP for Data platform etc. - Does this mean that MSFT will be releasing a bunch of security focused exams?

2. What happens to this exam with regard to the existing MS-500 exam? Does the Information Protection/DLP/CAS question set get removed from MS-500? In my experience that was the bulk of the questions fielded by MS-500.....
