IMHO you got it backwards. It's less of a question on efficiency than priorities. I doubt that if the request was too complicated to implement or the feature was for a very specific task (look at opening raw images in this very thread) there will be such quick response.

Larger teams suffer from the fact that everyone has number of requests and prioritising one over other gets even more complicated. Even a simple request like this might have to go through a pipeline.

Classic case of confusing correlation and causation. Large teams work on large projects. Large projects have large audiences which attract large numbers of requests. The smallest change in the world is going to get lost in all that noise.
