That would make the code fragile. Should be avoided as much as possible
as a form of aliasing. Compare:
procedure A (X : Integer) is
procedure B (Y : Integer) is
begin
X := 1; -- We know we are going to call it with X!
end B;
begin
B (X);
end A;

Defaulted formal package actual part:
generic
package Foo is new Bar (<>);
package Baz is ...
-- What were these actuals in Foo?
This is one of most useful features used to reduce lists of formal
parameters and simplify instantiations.
