Using the same logic I can claim that Ada has specific facilities for
managing heap based objects, so one should avoid putting data on the
stack :-) :-)

Reality is that either is possible, and that the choice made will depend
on the problem domain, requirements and local standards.

In this example I see no problem in using the heap. I you are really
affraid of undeallocated memory, make the type controlled and override
the Finalize procedure.
