Why was metadata removed from a previous version of async-task?

While I was browsing older commits for this crate, I noticed this one, where the original author removed metadata. Recently, we merged #33, which added metadata to tasks. Why was metadata originally removed from tasks? If the reason is still salient for the current version of async-task, we may want to revert #33.

I don't know the context of that commit, but if I look at the examples changed in that commit, I see that the type aliases were defined every time. (also, there are a lot of "()" arguments) I guess such a lack of convenience of APIs is the motivation for that commit.

That makes sense. Our new version aliases the metadata to () by default, though, so we should be alright.
