Bug Description
For now if the L3 agent change the agent mode (dvr to dvr_no_external, or dvr_no_external to dvr), the floating IP traffic will not recover. There is a mannully workflow to achive the transition, but it will need to shutdown the router during the transition. The backwards is obviously the floating IP under the router will be shutdown for a bit long time (admin state down/up). And the floating IPs not related to this compute host will be influenced as well.
So, IMO, neutron should support such agent mode change for varied cloud deployments.

I don't think that this is an RFE which needs any approval.
IMO we can treat this as a improvement of the existing functionality.
