This overhead is mandated by the spec's reliance on promises for buffer management, completion, and backpressure signals. While some of it is implementation-specific, much of it is unavoidable if you're following the spec as written. For high-frequency streaming – video frames, network packets, real-time data – this overhead is significant.
Another way to approach the linear combination is to look at it geometrically. This is where the idea of barycentric coordinates can help. A barycentric coordinate system describes the location of a point as the weighted sum of the regular coordinates of the vertices forming a simplex. In other words, it describes a linear combination with respect to a set of points, where in -dimensional space.
