At Sloan our expierience was that cookie crumbs did not really result in usefull intuitive navigation for dotLRN. We just use the portal page navigation in the header. We parameterized whether to display cookie crumbs or not so that can go back into OACS core.
Funny, I've played with SloanSpace V2 and didn't even notice you dropped the cookie crumbs. How strange! Good idea though.
Anyway ... the plan for OACS 4.x where "x is not much greater than 5" is to kick context_bars upstairs to subsite master templates where they can be ignored or not as the site designer pleases. Same thing with HEADER LINES. This gives more control than simply turning them on/off (master template can choose just how to display the breadcrumbs etc).
This has been talked about off-and-on in various threads for ... forever. Hopefully we'll get to it Real Soon.
