I already did, that thread 'tis a large part of why I'm somewhat irritable in relation to this topic today. "Huge source files are inherently bad because they provide no hint as to the modular breakdown and encourage excessive coupling between subcomponents" is just such a basic assumption of physical software design that I'm completely dumbfounded that people are questioning it.

If the objections were "I think this particular proposed breakdown is bad", it would be one thing, but most of them aren't, they're "I don't think it should be broken up at all for stupidly trivial reasons that have nothing to do with anything".
