Amen, brother.
Actually, it bears fruit daily. Any suite of application built around a
common database is reusing the same data model. The ugly problem is that
it's a relational model most of the time, and winds up having to be mapped
into a set of hierarchical objects *by hand*. I'm not going to hazard a
guess as to whether the process could be automated if the data in the object
hierarchy, with many of the attendant constraints, was represented as a
schema. It couldn't be any harder, however.
