Hmmm, with well chosen, thought through abstractions, which only presume the minimum they need to presume about their usage, the frequent changes you describe are not a given.

The question is, what it is, what frequently needs to change and why no appropriate abstraction has been found to reach stability.

We're talking about a huge web framework here. Your comment might apply to small isolated pieces of code. But Django is built on top of thousands if not millions of abstractions. It's absolutely unreasonable to think that it won't change.
