Public bug reported:

As part of [1] and [2], support was added to load service plugins at
start-up.

Specifically [1] added the 'auto-allocated-topology' (aka 'get me a
network') as a default service plugin for neutron.

However, this auto-allocated-topology when loaded as a default service
plugin does not appear to extend the network resource it defines [3];
adding a 'is_default' attribute to networks.

Therefore there's currently no way to set a network as default:

Note -- that from my logs I can see the extension being loaded:

Perhaps the extension manager extend_resources() is not called in the call-flow of loading default service plugins?
