I asked this question, and in the interest of searchability and the like, I'm curious if there's interest/benefit in using a tag for this feature.
The tag on SO:
Not having the tag on existing questions does make it harder to look for questions that may need to be tagged with the "new" tag if we implement it. But some other questions that would benefit:
Like I say, not a lot of benefit, but it does get a bit of an ask on SO so I figure it's worth seeing if the site here wants to add the tag too.
