You're wrong, the 3) is here done automatically, those scripts do not care about this. You are trying to make assumption those scripts care about more than yours, which is not true.

it's a bit different: Your approach requires distributing all the zones (not just the bind config) across all servers, while others just distribute the config.

Also, the fact you don't increment serisl number makes your design much harder to detect and fix errors, while DNS zone transfer mechanism takes care about that automatically.
