Right, we agree. If there are more/other contexts that might still be OK.
IMHO, if the programmer is removing a context that is still needed, that is

The "problem" was that your mail was intertwining both aspects.
Sure, the can be a simple setup in the C++ bindings, once the SAGA semantics
are clear...
