In reply to Thomas Ehrig.

Yep, tickets are generally opened on Meta Trac. This is probably one of those things that need some larger discussions before going on Trac though. As far as I know, there hasn't been much discussion on the overall idea (outside of better demo data), so discussions like this one here in the comments is important because they tend to get people's creative juices flowing.

If I have a little time, I'll outline all of this in a blog post.
