The current optimization is useful IF you have a lot of first level

me as a severe case of premature optimization to design with them in mind.
It's equally a KISS thing.
The current design is a complicated tradeoff to cope with an O(k)
requirement for DNS querying. This is unfortunate, it would be desirable
for an "obvious" and simple requirement to be simple to implement. This
is not premature optimisation, it's just robust design.
(Still aware that there isn't a good way to do what I'm getting at.)
