Out of curiosity, can you explain how relations are processed also ?
Is this relevant to look for a representative point for a relation or a
more complex search have to be done for specific members (roles) ?

I don't know Shapely enough to say if it can handle this standalone and it
would be greate to elaborate a bit what is done from line 260 to 280 of
