No, that's not at all what an interface is for. An interface is nothing
more than a contract which specifies what methods its implementors must
define, it is not a sneaky way to implement multiple inheritance

If it will never change, there is no value in including it as part of an
interface definition
Some libs with a lot of constants define a dedicated class for them,
others implement them in a parent class, both are valid strategies which
make sense in different situations
