Topic on Extension talk:AbuseFilter/Rules format

I (and probably several wiki admins) prefer a "user age since first edit" variable being added. When will it be possible?

Please file a request on phabricator to request a new feature like this, though it would likely be expensive to implement (user age can be easily detected from the `user` table, age since first edit less so)

Alternately, since nobody as of now has had the need to do that implementation, same work could be made by a MW extension that adds above-stated feature to Abuse Filter (if it even allows to be extended) which creates a new metadata table. I also thought about Extension:Editcount or something, or using MW's own cache (if it even exists) to store that info, but I have currently no accurate idea of a possible implementation.
