Wouldn't it make more sense to describe what "2.12+ job lifetime
management semantics" actually are? Maybe then it would be easy to find
a more specific name, too, like manual_completion.

In fact, I wonder if the opposite flag wouldn't be nicer, i.e. having a
bool auto_completion (or finalization or whatever that extra step was
called in the final draft), defaulting to true.

Also, the comment style in this header is already pretty messed up, but
I think the styles that were originally meant to be used there, are

    /** this one for single lines */

    /**
     * and this one if things get a bit longer
     * and you need multiple lines.
     */
