The proposal shows an example on how to isolate environments without duplicating some code. It acts, more or less, as a template for the architecture which you render it according to the values (environments/accounts).

I agree it isn't a simplest way to do that, but I don't think that it add as much complexity this. Perhaps it could be more laborious for the point of view of architecture, but it could be easier to handle and maintain.
