Hmm, this should be easily detectable on qemu side I think.  If
num_of_monitors (for a non-qxl card) is > 1, then we have an old,
non-filtering spice-server.  If num_of_monitors == 1, then it is a new,
filtering spice-server.  Or a single-head channel configuration, in
which case it doesn't matter whenever it filters or not.

So this should be fixable without causing too much compatibility pain.

cheers,
