In many cases the factory classes are just wrapping the creation of a
specific Filter/Tokenizer. Often these Filter/Tokenizer are even provided
by Lucene. Delegating in these cases seems almost silly.
More interesting are actual Filter classes provided by Solr which are not
 from Lucene, for example SynonymFilter or TrimFilter. Here we have actual
logic in the implementations and one could consider delegation. Here also
lies the real additional value of the framework and you would like to keep
in sync with the Solr work instead of forking.
