Well spotted, we definitely ought to work for something more coherent.
As for Paddington I would keep the two tube stations separate from the
mainline station. The fact that there are two stations called Paddington
is invariably confuses people who might expect that this is a practical
exchange point. In fact the old Metropolitan Hammersmith Line station is
not really a decent exchange point except for some local mainline
services: it's also a nightmare with a decent sized bag.
St Pancras is effectively several stations under one roof: the Eurostar,
Midland Mainline and the Thameslink services are pretty much independent.
Working out a way to represent these individual components, the
relationship with the underground, location of services (ticket offices
etc) and suitable pedestrian routing through these stations would not
only help for other complex transport exchanges, but offer real value
for users of OSM. The walk to/from platforms 12/13/14 of Paddington to
the Bakerloo & District/Circle line platforms is a not inconsiderable
part of a cross-London transfer.
On the other hand, something like the tagging of Zurich Hbf is probably
too complicated for an average contributor to want to contemplate:
