"Official" is what is used by data consumers - this is the case for the simple scheme, as there are 
3D renderer in the field.

The 'simple 3D' tags are used in addition to the other tags like width and height, so you can keep 
using the tunnel tag of course.

However please consider that 'simple' means it is not a fully fledged CAD system where you can 
represent every little detail. It helps to show useful 3D-outlines of a town.

At some stage it might collide with the interest of Indoor mappers, who want to represent indoor 
rooms and support indoor routing, most prominently in complex railway stations.
