I think the point is that they are _not_ equivalent.

Ada.Exceptions.Exception_Information is defined in the Ada standard,
and we can hope that a "newbie" will be aware of it.

GNAT.Traceback.Symbolic.Symbolic_Traceback is only defined in the
GNAT documentation, apparently we cannot hope that a "newbie" will be
aware of it.

So if our hypothetical lazy newbie tries to get a stack dump from an
exception, they will succeed with the "non-free" compiler, and fail
with GNAT.

Personally, I always read the GNAT documentation when I get a new
version of GNAT, to see what new goodies are available. Any newbie
worth their salt will do the same!
