So what? GP was complaining that a monolith cannot possibly have 5 boxes. (It must have exactly one, I guess, in their vision). You can totally have a monolith that runs the same code base in 5 different "roles".
If they did package the same exact codebase in a single monster binary and ran it that way, calling it a “monolith” would be even more hilarious but that’s not what they did
