Hm, thinking again about it and looking at all the editing tools, 
symbolisation dialogs, labeling and plugins, etc. that are based on the 
assumption that a layer has a single geometryType, it seems to me this is 
something for QGIS 3...

Whereas the filter approach for OGR is something that would be includeable 
pretty soon.
