Although I hardly ever find anything useful on StackOverflow anymore I think this is maybe partially overthinking the problem - for example in the case of versioning - if I have a question but I find an answer that does not work and is several years out of date if i were clever I would do something like say

How do I solve problem X using version Y of Z.

In some cases people encounter older versions of technology questions and make a new answer saying updating for version X of the technology - I know this happens because I did it myself for a Gulp question and got a good number of upvotes - even though I could never actually get the accepted answer of course.
