to me that it's sensible to try to control that from outside the

Right now I see an significant advantage of such layer: two possible extension of dictionary (filtering and storing original form) are independent from nature of dictionary. So, instead of modifying of every dictionary we can add some layer, common for all dictionary. With syntax like:

CREATE/ALTER TEXT SEARCH DICTIONARY foo (...) WITH ( filtering=on|off, store_original=on|off );

Or per token's type/dictionary pair.
