   Application layer validation can prevent it, but the question is should we have logic in `WildcardQuery.toAutomaton()` to avoid consecutive '*' which is not a valid case. Especially because the impact of not implementing an application layer validation by a consumer is very high. Excessive memory usage could lead to denial of service.
