On the contrary, I think it would be quite easy to maintain. Let's say you have a bucket in place in 20 different areas. If you have to update that content, you only need to do it in one place. That content may reside within widgets, on pages, in custom post types, etc. They could be scattered throughout the site but you only have to update the bucket in one place. Also, no they are far more than just glorified text widgets - you can put any kind of content in there, including HTML formatting and media - anything you could put in a post you can put in a bucket.
