A better way to do it is apparently to put the points into a (non-vertex) buffer and do (batched) drawcalls for large numbers of vertices with a kind of manual instancing. Basically looking up what amounts to instance data using gl_VertexInput/6 and vertex data using gl_VertexIndex%6 (or 4 instead of 6 for indexes rendering). Note that you can't do this in WebGL, at least WebGL 1.0. (Also, be careful about assuming things apply to “most” GPUs!)
