I've noticed that the "Good subjective, bad subjective" notice appears to be attached to this answer. I'm unable to find any other examples of it across the Stack Exchange network currently, but I had thought the notice is typically attached to questions. Is that the case, and The Workplace is deviating from the standard? If so, why?
The post notice options/comments are the same for Answers and Questions:
The reason you usually see Insufficient Explanation on questions rather than answers is to try and keep a thread, rather than a specific answer, focused and good-subjective.
In this case the question didn't appear to be attracting multiple bad-subjective answers, just the one. In addition, adding the post notice to the answer generates a notification (I think) to the answerer, making it actionable. Those last two reasons are why I post the notice on that answer. At least I think it was me.
As a side note, if you see a question or answer in need of one of these notices, flag it with an "Other" flag and explain which post notice the post needs and why. If your post has gotten a post notice and you feel you've resolved the problem with the post, flag it and a moderator can review and potentially remove the post notice.
Going through Review/low quality posts I converted this answer to a comment. The entire content was:
Yes. You lose nothing by asking for details.
