You are correct that those features are not yet supported. Here's a link to the debug page that shows what is and is not yet completed: http://wiki.eclipse.org/EDT:Debug (I just updated it to be more obvious what is and is not done).
Right now the push is to solidify the core components: add remaining language changes (these can be breaking, so the sooner the better!), improve extensibility, and introduce eglars.
I can't say when debug will see more attention, but I personally can't wait to add hover value support (I didn't realize how much I used it until it was gone). If there's particular enhancements people are looking forward to, I encourage you to add comments to the bugzillas so that we know what's most sought after when prioritizing.

Thanks for the information. "Hover value" support is number 1 on my list. It's one of the few remaining awkward moments in my "Calling RPG from EDT" video ... showing the seamless tier-to-tier debugging but then having to dance around the lack of actual debug features. Hover to see value is one of those "see, it's easy!" things that I like to be able to demonstrate.
