Genuine question, what would putting StackOverflow first improve compared to running "!so query", redirecting to SO's own search? These bang notation commands are often easy to guess, similarly !gi (I use it often, maybe should try more of DDG Images after reading the OP), !gscholar etc. I do like having an alternative general search engine, for one. So imposing a "coding" restriction would be a little sad. Maybe bangs could also indicate topics inside normal search. (edit: sorry, already suggested by a sibling!)
