It's weird hearing people say not to focus on cleaning modules because they're a waste of precious resources. Down the road, the code is all you've got - you must keep it in as good a shape as you can. The more "technical debt" you acquire, the harder it's going to be 2 or 5 years from now to stay competitive. Hacks might sell version 1, they might even sell version 2 and 3, but come versions 4, 5 etc. it's going to be increasingly hard to add features and fix bugs without breaking the whole thing. I've been on two such projects in my short career and it wasn't fun. It's one thing to work with a complex codebase, and it's completely another to work with a badly mentained complex codebase - it sucks the pleasure of programming out of you.

As I've said - code is all you've got in the end, and if it's good, the shipped product will reflect that.
