I have some concerns about the notifications that were just introduced for topic archiving. Quoting myself from here:

The talk page discussion archiving notifications that were recently introduced don't strike me as particularly helpful, and I'm not sure I'd suggest including them on by default. Most of the time, it seems the subscription transfers to the archive page, so telling me I might no longer get notifications for it seems misleading. On usefulness, most of the time, it seems that discussions have naturally concluded by the time they're archived, so it's just a nuisance. And in the times when things are more dicey, I worry that the notification could spur participants in a dispute to take up again an issue they had previously dropped, leading to WP:STICK violations. Lastly, when I clicked "stop getting notifications like this", it didn't give me any confirmation feedback, so I wasn't sure it actually worked, or how to turn it back on again if I wanted to (although I managed to find it in the settings when I searched).
