I think proxy voting in the past was used in two cases, one is the one you described, but more commonly to be able to vote if you are not present.I understand that proxy voting allows people to delegate their votes, which is a great thing: Here, I don't have the (time|expertise|whatever) to decide on my vote, but I trust the judgement of this other colleage; I'll give him my vote trusting he will use it well. This allows for higher and more qualified participation, and it would be a step back to lose it.
Sincerely,
Hans
