In general I think that we end up defining different symbols for 
different geometries anyway, i do not see how a point and an area can 
have the
same simbology; also there are specific postgis functions that make 
sense to use for specific geometry (i.e. ST_Area).
I do not want to say that i'm against the idea of mixing geometries, but 
to me it sounds a bit like loading "varchar" and "float" in the same column
and eventually ending introducing more complications than benefits, just 
my opinion,

best, Roy.
