It really makes life a LOT easier to do it that way. It can create some
quirky downsides where different people create the sections to replace in
different ways, and operational confusion (Is this section under automation
now or not?) , but it's still light years ahead of trying to build a
monolithic template from scratch.

Working section by section also makes it much easier to handle deltas and
exceptions for different sites and locations.
