C++: Do auto-generated classes need to be final?

[pavel-kirienko]

From Matrix:

• I found myself needing to subclass a C++ class generated by Nunavut, then I discovered that the generated classes are marked final. Would it be frowned upon if I proposed to remove the final specifier or to make it optional? (inb4 fix your codebase rather than breaking nunavut)

• I think this could be made optional but it does lower the availability of some optimizations and puts different constraints on the classes (e.g. the need for virtual destructors if non-trival, et-al). Can you open an issue against this so I can evaluate it?
