I was looking for comments from bridge driver maintainers to see if this was correct approach or not. It was not ready for bindings review yet. This was misjudgement from my end. (DO-NOT-MERGE tag should have been there I guess..) I will adhere to proper flow for RFCs as well from here on. Will resend this properly. Thanks. -Jayesh
