Although you've already done this, I would definitely request an attribution. Yes, the code is in the public arena, so you cannot derive any direct financial benefit from it. However, you can derive indirect benefit.
Me, I've been offered three (four? I can't remember ...) jobs as a result of maintaining PDF::Template and Excel::Template. I'm pretty sure merlyn has received consulting contracts for similar reasons. I can't imagine what brian_d_foy or Elian or TheDamian could ask for if they wanted a position in the OpenSource world.
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
