Mmm, I did myself. And if you ask me you hit a bug... :-(

It appears that 'cascading' just works for at least WMS.

BUT... cascading my test WFS fails because it looks like it 'rewrites' the returned GML, resulting in invalid xml/gml

IF the original features had a 'namespace' (in my case: test:provincies), apparently QGIS adds  it's own namespace  (qgs:) to it, resulting in
invalid xml (not more then one ':' is allowed), AND making the gml at unreadable for OGR/GDAL (while it reports the right layers, it cannot read the featureMembers: (see the "qgs:test:provincies" parts):

I created an issue for it:
