So, is it possible to make question like this to be "objective answer"-safe, and how should it look like?
To make it "objective-answer" safe, you'd have to stop requiring so much speculation about what you need. Furthermore, by asking for a one-size-fits-all solution, you're venturing into the classic "best practice" bad assumptions.
Perhaps the best answer to the "question" is to provide some pointers to complex questions that have exemplary documentation.
I would like to hold up these questions as examples of how well you could document your problem so that others can effectively and accurately assist.
