I'm really not sure how something can be archived without actually doing something about it. So I guess if it is resubmitted then it has to be active again...
One of the key things for MathCAD in what I do is presentation of calculations for busy people, and some that are not looking at numbers all day and just want to find the section they are interested in. In MathCAD 15, we could create styles that were appropriate, the only thing missing was a table of contents. Prime seems to have gone backward in this regard.
The reality is for many who use MathCAD to document their engineering calculations and thoughts, the use of styles is almost absolutely essential. Microsoft word is a good starting point to see what it should look like. I don't want to have to mix and match programs just to sort out a simple documentation feature that seemed possible 20 years ago, but now seems almost impossible to achieve.
