I don't think we should be preventing this from recreating deleted categories for the same note I mentioned in bug 61994. If people are using these alternate cases, then it is reasonable to assume that others will as well and the category should be created as a redirect to the proper case/category. Redirects are cheap and this will allow the category redirect bot to go through and move members with the wrong case to the correct one while allowing people to easily find a category regardless of what case they search with or type in the URL bar.

That sounds like a separate bug. Regardless of the *reason* for recreation of a deleted category, it seems reasonable to assume that the action might be controversial. Flagging the category for human review would stop Babel AutoCreate from getting in the way of human editors that have good reasons to delete those categories, whatever those reasons might be. For example, with this feature, there would not have been a reason to file bug 33553.

I don't like this particular fix. There's a lot of ways a category could end up deleted and still be okay to recreate at some point. It looks like the code already respects salting, so that can just be used if necessary.

I'm not sure about this one either.

It's complicated to know if a category is recreated because now useful or because it's still unneeded.

For example, if three users register with a new language code, and the category were deleted as empty, the recreation could be useful.

At this stage, it could make sense not to use the Babel extension and to manage the categories manually.

I agree with Dereckson. Please see T63993. If, for example, we delete a category as empty because no one happens to speak the language right now, but later some user registers and happens to speak that language and tags his page as such, I think the bot should be recreating it. Thanks.
