Yes, although the generic approach could probably be more doable by adding a few 
conveniency methods to make the transition easier for 2D-only drivers.

For example, currently you'll find in a typical Open() method

poDS->nRasterXSize = x
poDS->nRasterYSize = y

In a generic multidimensional approach, this could be replaced by a

poDS->SetXYSize( x, y )

that would take care of setting nAxisCount = 2 and initializing the 2 axis.
