Recently, I asked a (now-deleted-by-me) question about the fictional use of a real spacecraft in a "hard" science fiction novel -- specifically, what issues / difficulties / impossibilities would be encountered in making a pretty specific set of modifications to serve a pretty specific fictional mission rather different from the mission this spacecraft served in real life.
While I admit to being somewhat clumsy in formulating my actual question, it would seem like if "what would make this pretty defined task impossible or require extra workarounds?" is unfocused, then a good many questions that were answered well with many upvotes would have been unfocused as well.
Should I have been more specific in defining my exact parameters? Or even taken it out of context of the science fiction novel? I got one comment that amounts to "in scifi, whatever the author wants can happen" even though this barely had any bearing on my question.
