ZD HC/Guide support for missing or archived articles

IMO, the fact that ZD doesn't have better URL support is somewhat shocking. Here are some examples of what I mean:

1. They don't support reasonable and sensible URLs (only weird IDs with broken slugs)

2. They don't support 404s when articles are archived or removed

3. They have limited support for articles that are renamed, such that only if the ID is present will it redirect

4. There are bugs in the URL mechanism that I've reported to ZD that still exist (weird character issues, dangling hyphens, no support for certain important and valid URL characters)

I'd really like to see some of these important issues resolved. How about you?
