I don’t think the length of the explanation is very relevant, and finding shorter explanations doesn’t seem like a primary concern. Explanations should be judged on what problems they solve and how well they stand up to criticism and competing explanations. And since I don’t think any explanation can be “final” or “100% true” or “guaranteed” or anything like that, the notion of a shortest possible explanation doesn’t even make much sense.
