wbntff oh sorry, I did check the discussion for any bug report before writing my post but I didn't notice your post had both a suggestion and bug report in the same sentence 😬
The lack of update for months is not indicative of anything wrong by itself. I personally have created many extensions that are so simple they will almost certainly not require any change until Flarum 2.0 gets released.
However while Nearata hid their public last login time my mod powers show they haven't been online in quite a long time 😅
You could try reporting the issue on GitHub, where there's a higher chance they get an email notification.
