Sure, please file a blueprint and submit a patch for this, I would review this for sure! :)

There are optimizations underway around this area. For example, we're looking at possibly collapsing the individual Linuxbridge and OVS agents into a single agent. In the context of ML2, this makes sense. I've thought a bit about collapsing the bridges from two to one and this is something which seems quite doable frankly.

Thanks,
