Don't forget that this is in the center of a large city, where details of a
building are really interesting.
To give another estimation that this won't impact the database performance:
any of these buildings has less nodes than employees are employed in it or
persons living in it. So, we still probably won't get more that 2*60 million
nodes. Compared to 300 million nodes that exist already, it is not too much.
And even better: most parts of the database are organised spatially. So you
won't be affected more than a degree of latitude or longitude outside France
no matter how much nodes are added there.
