You seem to be playing around with words. Perhaps I am guilty of sloppy
English when I say "interface is copied" when meaning "an interface
reference is copied". However, this does not change the underlying problem.
The problem being referred to is the functionality described here:
http://freepascal.org/docs-html/current/ref/refse44.html#x98-1200007.4
under the title "Interface delegation". The word "contained" does not
appear here.
As it should, contained interfaces are one way to solve the problem
there are other ways that are design/domain specific and yet again there
is the option(already given here) to use interface variables instead of
object variables, just make sure you set them to null on the destructor
to release the interface.
I see no rabbit hole or any other problem in the code posted so far
except perhaps lack of proper clean up which might be intentional.
