I will answer these two point at the same time:

The tool can import these data too, but the last time we discuss here there
were LOTS of opinions against these. We agree with you, and internally we
are using that information but from our point of view it a decision that
the local mappers must take. In [1] there is the same same town but with
building 3D data and rural parcels. In this case you will not notice much
differences as this is a very small rural twon where the buildings have
normally one level. In [2] and [3] you can see Cadiz [4] a big capital from
the south of Spain with [3] and witout [2] the 3D information.

In fact we can also have the all the historical changes but we do not know
how to code this information without completely screwing the actual data. I
am not sure about the acuracy of data previous to 2000 but we can extract
it. Exists any propousal in this direction?

In this case it does not matter what you have deleted because they sahre
the same geometry and tags :P
