I spoke with mpontillo a bit today about this bug and confirmed that with MAAS 1.8, IPs for devices are not cleaned up when the device is removed.
However, this doesn't help us to release 1.25.2, as we cannot release something that will break people running MAAS 1.8. This problem was most likely introduced in Juju in the fix for bug #1483879 (included in 1.25.1). I was able to recreate the problem of leaked static IPs with 1.25.1. I'm not sure why IP address exhaustion only recently became an issue with QA.
We can't really consider this behavior as the same behavior that bug #1483879 was trying to fix, as the IP addresses left behind before the fix would eventually have their leases expire and would be reclaimed. This isn't the case now, as the static IPs will never expire and never be reclaimed.
