Actually it does because the chance of hitting strange edge cases grow significantly, as do the runtime of your deployment, plus networking problems risks.

Running 200 servers will force you to automate everything and also handle (relatively) rare edge cases, meaning added complexity, huge up front dev costs, and a continuous dev effort just to stay afloat. Work has to be balanced in a clever way, making tradeoffs that you otherwise wouldn't need to make. The mental model shifts from individual servers to a whole ecosystem that shows emergent behavior (= things break in a totally new way).
Maybe some of that also applies to 4 servers, but to a way lesser extent.
if you do this with 4 or 200 machines, does not make a big difference.
