Tags are useful for lots of reasons. Accurate and specific tags; much more-so.
When a site does't have a particular tag, it's easy enough to add a new tag to an existing question.
But, applying a new tag to old questions is problematic, because it bumps the old questions to the top of the active question tab.
In my particular case: I've created a tag on a SE site that probably should have been created long ago. There are hundreds of old questions should (indisputably) have this (as their most relevant) tag. Some of these questions are good, but some are not-so-good, and many already have accepted answers. These questions do not need to be bumped.
The SE site in my particular case is relatively slow; it takes about 2 weeks to drop off the 50 most recently active posts.
What am I supposed to do here? I can see a few option, but they all have problems:
Not create new tags.
- no, there are some useful tags that haven't been created yet.
Apply the new tag to all of the old questions in one go.
- this will flood the active questions tab, which is obviously bad.
Apply the new tag to new and currently active questions only.
- this leaves hundreds of questions without their most relevant tag. The old questions will be harder to find, which encourages duplicates.
Slowly work through the backlog, only retag a few questions each day.
- this will take months, and continually restock the recently active questions list with a small number of questions that do not need attention.
- on a highly active site this is probably fine, but on a slow or moderately active site (as in my particular case), this will annoy a lot of users.
Request a new feature (possibly restricted to moderators)
- feature request denied (see Disabling bumping for retags by hi-rep users)
This (and related issues) have been a problem for a long time, as documented below. This includes some proposed (yet rejected) solutions. This problem exists across all SE sites and warrants a solution of some kind (possibly only accessible for moderators).
As is, the system for adding a new tag to old questions is broken.
