Your comments in comment #17 are mostly accurate, the exception being point b:

a) no api changes are required

b) BGP is NOT a pre-requisite for fast-exit. With BGP you can achieve synchronous data flow directly to and from the compute host. Fast-exit still takes the network node out of the outbound data path even when BGP is not advertising host routes, so you still get some benefit without BGP.

c) changes are required in L3 agent

d) yes there is a conflict with the use of address scopes and the enable_snat attribute on routers that requires attention. However, in my opinion is not a DVR-specific issue and should not be thought of as a blocker for DVR fast-exit.
