Bill, I'm not sure I totally understand what you want either, but I think I agree a little to what I think you want. I think we should un-link the "about/uncertain" button so we have an "uncertain" button and a "circa (or about)" button because they really are two different things. Then, it would be good if we could somehow link the information in the data fields to one or more of our sources. But I don't expect any of that to happen anytime soon because either of those would be a major undertaking by those who write the coding for WikiTree. Keep in mind this is a free, low-budget site, so major changes don't come quickly. And, even if those changes were possible, marking any status button or connecting a status button to a source doesn't really explain the thought process involved in determining an estimated date. The best solution for any of us is to use the biography to explain how a particular estimated date was derived and why it was placed in the data field and why a particular status button was selected. To you, it may not be the best way, but currently it is the only way.
There are many things which many WikiTreers do and don't do which "professional" or more skilled genealogists might or might not do. WikiTree is for everyone from the casual hobbyist family researcher to the professional genealogist so there are wide variations in what profiles do and don't include. If someone like you, who strives to do things like professional or more skilled genealogists, have constructive suggestions on how to improve our profiles within the current constraints of the system, G2G (this forum) is the place to share your expertise. We can always learn new ways of doing things. I'd love to see you share examples of your work so I can know how to make the profiles I manage or contribute to better.
