We all agree with you !

Yes, it one of the issues we are talking about on the talk-fr.

Yes, at the beginning of the cadastre extraction, it has been a kind of 
fever.
And we have added warnings, explanations, tutorials, examples... (and we 
will add more)
But what is already in the database must be cleaned, and sometimes 
erased for better data.

Yes... we know, and are working to avoid it. Hard work !

But we are also proud of spots like
