At the very least, if you keep the ones that germinate quickly and pitch the rest you will be selecting for lack of seed dormancy.
I would have said that the chapter doesn't necessarily support your theory because both the "dormant" and the evergreen species benefited from stratification.
Another possible fly in the ointment is that foliage habit isn't necessarily fixed, in other words what appears to be deciduous ("dormant") in one climate may be evergreen in another for example.
