Yeah sure let's reduce my advice to a hyperbolic niche situation. This has nothing to do with performance. I'm explaining general rules for designing maintainable systems - it is possible to follow them and write performant code at the same time. It is also possible to break them if necessary. Though it usually isn't a problem at all, you're just reducing it to absurdity in order to make your point.
