No. The last time I played with it the cluster strategy didn't exist :-)

However I am having some trouble to get the number of tiles which are expected to redraw and comparing this to the responses retrieved. Also, I would need to optimize the grid strategy to not retrieve new features if the new bounds is contained in the previous bounds, so that it is a bit smarter in retrieving features.

That'd indeed be great.
