It's true that many architectures provide registers designed specifically to access stack memory, but it is still memory--it's just that those registers provide more convenient access to the stack, though a lot of that is also legacy baggage.

Accepted. My knowledge of computer science is very inferior. But is it
not true that Bjarne Stroustrup himself proposed RAII to negate some
of the problems caused by heap allocation. Also, you can refer to this
Polymorphism without Heap Memory | Embedded Systems Experts which
describes problems associated with heap. Many of my concepts may be
wrong but heap is definitely source of lots of problems.
