I have tested a quad mesh of another product and I'm not really excited of that idea at all. To be fair so, a polygon size limit could be useful. Some application have problems with polygons larger then 100 vertex, which can happen in some cases. I haven't found a tool where I can set max poly edge count, but in Modo you can select all polygons with more then 4 vertex and make them quad or tries with a single click. Can be useful.
Ideal max size of polygons so, would be between 5 and 64. So this could be really useful.
