That's obviously much simpler! I was under the impression that 'title' was only for use in front matter, or that if I used it elsewhere, then it didn't show the number but that the next use of 'chapter' would increment as if it had a number. I was wrong!

Use \title (or \starttitle[title={}]) for unnumbered and \chapter (\startchaper) for numbered.

If you need the unnumbered chapters in your ToC, you must add them like \setupcombinedlist[content][list={chapter,title}]

You can setup most options for both using \setuphead[chapter,title][...]
