We've seen and discussed this a lot over the years. Most recently, Ewan posted another meta question tangentially related to this where a string of questions were down-voted. The answer to the meta question basically says that the questions ended with "what is the best practice" or "what is the industry standard practice?" with the recommendation to just edit that part out if the post is otherwise good.
I've been reluctant to do this because I feel it fundamentally changes the desired outcome or answer that the OP wants, but Thomas Owen made some good points and I'm in; I'll start editing out those troublesome bits. But still, I have doubts.
When is it acceptable to edit a post and remove phrases asking for best practices or industry standard practices?
