Library-ish sharing is fine but in terms of interface, I think it'd be
better to keep them separate at least for now. Down the line maybe
these resources will interact with each other in a more integrated way
but I don't think it's a good idea to try to design and implement
resource models for something like that preemptively.

Thanks.
