This sounds a lot like the days in web dev before Ruby on Rails came along.
When they (and django) took the web dev world by storm they were prescriptive and told developers how to do something, not just giving them a bunch of tools where you had to build your own app lifecycle, usually massively over-engineered. A whole load of mental overhead disappeared.
Just before Rails, etc. everyone was going on about Factories and the Gang of Four and people were building crazy startup patterns on their webapps using Singletons.
