I played a bit with what we have and in a next upload you can do this:

\startexceptions[de]
au{f-}{f}{ff}(f\zwnj f)asse
\stopexceptions

\showglyphs

\starttext

auffasse

then is like:

au\discretionary{f-}{-f}{f\zwnj f}asse

\stoptext

Just an experiment. I don't know when there will be an update because 
first WS and I have to test and double check some new stuff as we don't 
want users to suffer too much from a couple of fundamental new features.
