Please publish.

I would like to strongly advocate publishing this document as-is:

o Weighing cost vs. benefit it is better to have some warnings produced
  by missing $TTL statements than errors introduced by $TTL statements
  in older BIND versions. Recommendation of the use of the ``latest''
  version nonwithstanding. Please remember the working title and that
  the target audience may not be expected to fetch and compile those
  ``latest'' versions themselves.

o A design criterion was that the document be ``short''. Any further
  discussion about peculiarities of certain major or minor releases is
  not helpful.

o While there is an issue with $TTL, the document in its current state
  is not broken. There is always some issue not covered in all detail,
  but that's by design.

o Even RIPE documents are not set in stone. Should the operational
  experience with that document suggest that the $TTL or any other
  issue do not work out, we can and should review and maybe revise it.

o With regard to working group economics I would prefer a living
  (i.e. published and hopefully used in real life) document over
  a draft that circulates forever heading for perfection and never
  hits a ``real end user''. We need that kind of feedback.
