I assume the both. In fact TYPO3 v5 is a huge exercise for developers. 
An exercise I would not be able to take today. And it *must* start with 
bad design (in terms of software architecture). It is a widely accepted 
fact that is is impossible to make a perfect design and then just 
implement it (the so called waterfall methodology).

But for v5 I would add

- the developers follow proven best-practice of software development

The v5 team started with small pieces of the puzzle and continuously 
refactor the code towards a better design while adding (well tested) new 
functionality ([1,2] for the interested).

Is fact that some of the v4 core parts (namely tcemain and tceforms) are 
not rewritten again and again a sign of good software design? I don't 
think so. It is just real world without the possibility to change.
