All the things he listed that WordPress doesn't have are the reasons why I like it. With the exception of better caching/CDN integration, I like that WordPress is simple, straightforward, and super hackable with plugins and theme functions. A lot of people don't even know all the capabilities. Few know about the WP Transients capabilities, for example. They're quite powerful and useful.
Glad I could help out. The Codex is in great shape, I think they just have to prioritize their time and they don't have huge human resources to focus on everything. Focusing on the Thumbnails section, for instance, might serve more people than the Transients API. But the Transients stuff is pretty neat and there are other little hooks and functions that really do a lot :)
