There is the Simple Haskell initiative, which encourages what you're talking about, but no flag or pragma that says "this project uses simple Haskell". Obviously, simplicity is in the eye of the beholder. Fancy type features do have their use cases where they make types more expressive, the code safer and even simpler, so long as you've internalised how they work.
In the UK the Consumer's Association and Which? fulfil the same role, and has been going since the 1950s. Before the internet the magazine was a part of everyday life for many - if my parents were going to buy something like a new washing machine my mother would go to the library and find the relevant issue. Online you can see some of their reviews but I think you need to subscribe to get all the (very rigorous) detail. The CA is a charity and has a sort of NGO status, able to issue a "super-complaint" if some industry is not working for consumers. I suppose I'm a lot less careful with money than my parents were, I never use it.
I've just finished Pamuk's novel A Strangeness in my Mind, where the protagonist is a street vendor of the traditional Turkish beverage boza. Boza is a mildly alcoholic fermented barley drink considered ok for Muslims to drink. The gradual disappearance of boza sellers in the street is an index of the changes in Istanbul and Turkish society in the late 20th century, really enjoyable book. From what I've read I can imagine it's an acquired taste.
