Indeed and breaking out logic into more global scopes has serious downsides if that logic needs to be modified in the future, if your system still needs to support innovation and improvements, downsides not totally unlike the downsides of using a lot of global variables instead of local ones.

Prematurely abstracting and breaking code out into small high level chunks is bad. I try to lay it out from an information theoretic, mathematical perspective here:

with some implications for testing:

It all comes down to managing code entropy.
