I wonder, though, why we need this in HDF.

If we have a shared dimension without coordinate values, how is that
different from an unshared dimension without coordinate values (which
is what HDF currently provides?)

we need shared dimensions: almost all higher level Conventions rely on them. they dont always rely on them for just coordinate variables. Generalizarions of coordinate variables also need shared dimensions, but cannot use coordinate variables.
