I'd take that wager. 95% of the time, passing more arguments into a subroutine than it expects is a sign of forwards- (and sometimes backwards- ) compatability. Other times, it's a sign of API compatability. For example, I've got a templating module that works with more than one rendering engine. There's a given function that both engines support. But, one takes (and handles) a foo parameter and the other doesn't. If I cannot pass the foo parameter in (to be silently ignored if necessary), that's a sign of bad assumptions.

Be liberal in what you accept and strict in what you emit.

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.
