You really hit what I was referring to ! I think I saw the same article and got me thinking to dig and find out that it's now common knowledge to do that for the sake of 'clean code'.

That's why I chose this bold approach in my writing, I fairly think that the context of using a repository is clear enough that you will eventually know you need to create one and abstract it in a different class.

But using it everywhere (like it's trendy now) is useless...
