Hi! As mentioned in the thread for GIP-0034, we had a discussion among core devs last week about GIP-0037 and GIP-0034 as alternatives to enable rewards on L2.
The consensus was that GIP-0037 is the better alternative, so this is now the course of action that we will recommend to the Council 
The L2 deployment without rewards is happening soon, so after that we’ll be working to get ready to deploy and enable this change too. Feedback is still welcome and appreciated, especially if you see something in this GIP that we may have missed or could be improved.
