I am consistently impressed with the thoughtful API abstractions django develops. They were a little late to the game on this — you had to use other libraries to do WebSockets for a while. But they did this right.
I think of that as a “senior developer” skill which is easy to underestimate since it doesn't directly translate into tons of commits but is so critical to the long-term success of a project.
Can you explain what you mean by this?
