You've been missing the point of bheadmaster's posts, which (as it seems to me) was to show that "you can compose context-aware code with context-oblivious code (by passing context.Background()), and vice versa with no problems". Bheadmaster gave some proof of concept code showing how to do that. The code might be somewhat inefficient, but that doesn't invalidate the point. If you think there's a more efficient way to compose context-aware code with context-oblivious code, then the best way to make that case would be to explain how to do so.
