I dont like the "impure" label. But the guts of it is right. Most software solves a business problem. Even the "pure" ones could choose to deliver value sooner with tech debt.

Maybe "practical" engineering is a better label?

You could go for "pragmatic" but then it's taking sides :-) If instead of "pure" you use "purist" you completed the loop!
