Comment 1 for bug 2012332

The request sounds reasonable request to me. The current API requires users to fetch the current set of allowed-address-pairs and then update it. We had the similar issue around router routes and we added "router routes (atomic) extension" [1]. I think we can use the similar approach for allowed-address-pairs too.

I am not sure the current API is "time-consuming" as described in the bug description though.
