This seems like a method for overengineering that treats every problem as a class design issue, every class as a contractual interface, and prioritises grand designs, verbosity, fragmentation and the proliferation of new nouns, over organic growth, readability and common sense.

I can see the value of rigour in API design at system boundaries, and LSP seems like a fancy name for "don't do weird things" but does the rest of it it have any merit outside of class-maximalist languages like Java, C# and C++?
