shouldn't finalization be abstract now that it's empty?

I thought about it. If it's left abstract you can't call super.finalization() in the deriving contract, which we want everyone to do to make sure the whole finalization chain runs.

The default
finalizationimplementation inFinalizableCrowdsalecallstoken.finishMinting(). This is orthogonal to having finalization logic. If one wants to be able to mint further tokens in the future, the defaultfinalizationfunction cannot be called. See decentraland/mana and how they worked around this:Since we want to make sure that all contracts deriving from
FinalizableCrowdsalecallsuper.finalization(), to ensure all of the finalization logic is executed, we have to remove the call tofinishMinting.The caveat here is that if a custom finalization transfers ownership of the token to an address, that address will be able to mint tokens unless the custom logic also calls
finishMinting. This is something that will come up in an audit, however.
