In general, there is no good place that we can know that we should be
reprojecting on these layers.

Where do you think the reprojection code would live in this case? I
don't like the idea of touching someone else's geometry. In the case of
a Layer.GML or some such, the format is creating the geometry, so it
never belonged to someone else to begin with, but with Layer.Vector and
Layer.Marker, that's less true.
