It's not that simple. Properties can be both hidden variable access as 
well as procedure access. Variable overloading is not allowed, 
because it causes a lot of issues, i.e.:

var a:word;
     a:char;

begin
   a:=1;
   a:='!';
   writeln(a); {what does this mean??}
end;


Property overloading gets you the same issues, i.e. in the example above 
you could replace both variables with properties and answer the same 
question.

Considering this, I do not think it can considered a logical extension of 
procedure overloading.
