Bookmarks are for really important stuff. Open tabs are for stuff I want to be able to easily stumble back upon, but I won't be butthurt if I dont.

It doesn't. When you reset it, they take very little resources until you actually load them.
Most non-technical users do this and then complain to IT because their computer doesn't work well. That resource is wasted.
