SUMMARY Currently the number of tiles can be quasi infinite, which however is rather pointless. Therefor it would make sense to limit them so that there's fixed minimum width / height for a tile or that tiles have a minimum size for which the edit controls still fit into them.
We could consider a minimal amount of pixels. I'll let the kwin developers respond about how feasible this is.
