Isn't there going to come a point in time when the whole 'Stairs' project will become saturated? That is, everyone who is going to join has, and certain game types will end up with cliques of sorts that just keep cycling each other. I wonder if we are near or at that point already. If not, where will new blood come from?

It seems that Rooks are the only ones with options to enter a high number of different stairs. I suppose it could be argued that, with over 20,000 pawns, there are at least that many possible entries into the experiment, but that is not happening, in fact not even on a scale anywhere close to it.
