My thoughts (as a self recognized noob). If there is going to be a discussion of the HOS and what that entails, people have to forget about what it was. Come up with a new definition without being hampered by what the old definition was. Start from scratch almost.
Now perhaps it ends up being what it originally was (or very similar), but take a fresh look at what people want it to be. Does it really matter now what someone did x numbers of years ago to get on the list? And perhaps once it is agreed upon (however that happens) maybe people on the list could be given an opportunity to "appeal" if they think what they did no longer warrants being on the list.
As an example, some people say it should be the worst of the worst. In response to that others have pointed to one person in particular (can't remember his name) who didn't seem to do anything much worse than Hustruck. That doesn't automatically mean it can't end up being the worst of the worst in a new agreed upon definition.
