Correct.

No, unfortunately, there isn't. However, I already had the idea of adding a
more detailed callback mechanism
where there's more information provided (e.g. from and to address, address
index, integrate link- with address callback
etc.). That would also fix the fact that currently, you don't know which IPv6
address has changed.
