Dear Philip,

Thank you for the review comments.

AFAIK, I used the PlatformLogger which was commonly used in that module.

Just to understand,

 1. Is/are there any bug(s) associated in getting rid of PlatformLogger
 2. Is there any new logger design/development planned in the near future?
 3. Any new common logger API(s) will be in place for the logging
    purpose in the coming days?

Could you please let me know.

Best Regards,
K Suman Rajkumaar
