At the same time it was a base class for all the other token classes. We have since made an EventToken
class to represent pure events. It remains public for some level of backward compatibility.
Generally, we have not pushed to make classes abstract, since concrete base classes allow for testing.
We've also avoided making classes final that we don't intend to extend simply (e.g. most actors)
because we don't want to restrict others who use the code too much.

Token seems like an excellent candidate to be an abstract base class since the documentation states that it should not be instantiated.
Any reason to not do that?
