Sorry, I think you mis-read the article. It contains no reference whatsoever to spare capacity, but to replacement satellites to maintain service as the fleet ages. I'm not saying live telemetry is good idea, just that there are already satellites up which could handle that using a tiny fraction of their existing capacity.
