Well keep in mind that you do not need a vault instance on every DNS
server, just like a CA a few servers would be sufficient. DNS key
rotation happens relatively 'rarely' so the dependency is not a huge
problem in terms of performance or management. There is the problem of
the heavyweight java-based infrastructure, but we already have that
dependency for the CA part, so it's not like we are adding anything new.
