I want to get rid of tag implications. I haven't been approving them lately because it's just so easy to go overboard with them (a pinup tag? what's next, magazine? published_work?) Aliases are easier because there's a simple test: equivalence. Implications on the other hand can create tags with thousands of posts out of thin air, for a tag that very few people might use. They're also much harder to revert, and the way they can create cycles with aliases is hard to detect. I think if a tag's important and relevant enough to be added, it should be added manually. I'd like to hear convincing arguments for keeping them.
