abstract class and interface classes

[j8Mo2yTq]

When declaring an interface using pure virtual functions is it normal or suggested to declare the destructor as virtual too or is it not usually done with interface classes.

See:

A class with a virtual function should have a virtual or protected destructor
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rh-dtor

and
A polymorphic class should suppress public copy/move
