Those are related; if small file performance will be enough for one
MDS to handle high load with a lot of small files (typical case of
webserver), having multiple acive MDS will be less of a priority;

And if someone currently have OSD on bunch of relatively weak nodes,
again, having active-active setup with MDS will be more interesting to
him than someone that can just buy new fast machine for it.
