Reasons are mainly historical. It would be very difficult to suddenly
change all delegations, settings of many customers' computers and so on.
Generally speaking, things which are dependent on many other persons.
Personally, I could get used to new format of files, hard-coded magic
filenames, absolute lack of manual pages, let this ugly and ridiculous
/service in the "/" directory and so on, but due to things which would
involve other peoples, it's definitely not an option, at least
currently. So djbdns is out of discussion. I must say it with sadness
because I really would like to use DJB software because of it's
