We have configurations for the ones included to the Snowball, namely
Romanian, Hungarian, and Turkish.  I don't know why the others are not
included but listed on the page as external contributions.  It might
be a good idea to wait for someone to commit them to the upstream.

I have checked the changes on the algorithms [1].  They don't seemed
to be updated much after 2007, but recently a new one for Tamil
language is added.  It might be a good candidate for a new
configuration.
