Configs are not simply about languages, they are also about stopword
lists and stemmers and parsers, and there's no reason to think that
one would be using only one configuration to create a single tsvector.

Different fields from within one document may require different
treatment.  Take for instance title, with stopwords included, and
body, with them removed.  Those two initial tsvectors can then be
concatenated together with different weights to provide a very rich,
and simple (relatively speaking) search infrastructure.
