We are not constrained in *any way* by the existing system, we just want to play nice with other namespaces and make it somewhat familiar to users.
Will it be greater if we can be compatible with existing DNS system, so that someone could setup a traditional DNS server (connect to chain as part of db), others can set to this DNS to replace original.
As in this way, it could be possible for the Internet to migrate from traditional dns tech to DAC-based DNS without influence user experience and user's habit.
I always wonder that the revolution can happen silently and smoothly, and it could be more powerful.
