The problem is always that easier setups also lead to more options 
(undocumented) that when explained lead to the previous code.

At some point we can thing of some 'common preset' but I'm not yet sure 
how to implement that.

btw, there is:

\setupstructurehead
   [chapter]
   [appendixlabel=appendix,
    bodypartlabel=chapter]
