I like for drain pans to drain completely but many don't. It is usually
not a problem as the slight amount of water that does not drain will
evaporate fairly rapidly if no water is draining into the pan. I would not
modify the pan drain.

I was thinking maybe some water in the pan prevents crud from building
up, or something like that. If there is no real use for it, then I plan to
make the modification.
