*I* find
     Null_Object : T;
confusing. A maintenance programmer probably doesn't know the class of
object that T represents, and the lack of an initialization looks like a
bug. You could "fix" that with a comment, but an explicit initializer works
just as well. (The lack of "constant" is also suspicious here; if the object
is a variable, it probably shouldn't be named "Null anything", because it
could change.)

After all, I often have:
    Null_Object : constant T := ...;
in my programs, where T could be any type.

If the object is a variable, it probably ought to be initialized with
something useful.

But I suspect being consistent is more important than any particular rule.
