I've never interacted directly with IBM, but I remember about 2 years ago, they had a talk at the Akamai Edge conference about how they dealt with bloated cookies. The company I work for has the same problem so I sat in to see what their solution was.
The problem they were having is that all the various IBM lines of business added so much garbage onto the client's cookie, that eventually their pages would stop loading because they wouldn't be able to parse the cookie.
The 'solution' is to detect when that's about to happen, and redirect the client to a page that warns them that their cookie is too big (because IBM made it too big) and give them a button to delete their cookie. They then continue to start over and stuff more garbage into the fresh cookie.
That kind of problem solving pretty much made me lose faith in them successfully doing much of anything anymore.
