I think there is a reason why people do that: trying to steer -those they consider- newbies away from patterns they consider bad, but at the same time this second-guessing can be annoying when you know what you want to do (
especially when the original question isn't actually answered yet it comes up in search engine results...).
I can't say if it is a good reason in general, perhaps it is, but it certainly is something i personally find annoying. I think answers should provide an answer to the question asked and then, after that answer was given, they could also give pointers for whatever they consider a better approach and why - this is important, IMO, for a public forum where people of all backgrounds and goals can read the same stuff.
But either way, LLMs IMO should do/provide what they are asked without trying to second guess the user (or at least, there should be LLMs that act like that).
