Just to clarify some semantics of the config format.
Is each individual 'remote' ID considered to be a single server,
regardless of the number of addresses it has?
For the notify case, it looks like knot will send to each address in a
remote ID in serial, and stop as soon as one replies. That suggests
the above semantics, but I wanted to make sure I'm interpreting this
behaviour correctly before I complicate my config by adding a lot more
remotes. I am currently treating each remote as an organisation,
lumping all of that organisation's servers together under a single ID.
