Take unit Typinfo for example where quite some methods take a TObject
instance.
The TypInfo methods can determine the exact type of their arguments, and
act inside accordingly.
If you have a method X that takes a TObject parameter how do you plan to
pass it a reference counted object when these and TObject are not
compatible *at compiletime*?
That's intentionally impossible in general. For TypInfo, a dedicated
method (override) can be added, or an untyped parameter can be used like
in FreeAndNil.
