I agree with the quick hacks thing, but I wasn't suggesting to manually(?) append these cheatsheets to the qqq messages, but rather to replicate that mechanism, with some changes in the pattern it uses to fetch the pages to transclude. This in principle addresses your concern about quick hacks -- unless the qqq thing is itself considered a quick hack. But if so, even though one wrong (is it?) does not justify another, I gotta say, while what you're talking about makes perfect sense and would be awesome, it seems like something that would take a while to be implemented (if ever). And on the meantime, maintaining consistency across translations stays a cumbersome task...
