The change of address is linked to the A-number, so a case doesn’t have to be pending for it to update. Last June, many people without an online account didn’t receive their TPS EAD extension notice. Most of these notices were sent to old addresses where they had previously filed their cases. That said, I haven’t seen anyone punished for not updating their address.

If I may, I'd like to make sure I understand your question clearly. Are you asking whether updating an address is the wise choice based on today's perspective, or if leaving it as it is would be smarter? If you live in a cheap and diverse apartment, there's always a risk of someone knocking on your door, whether you change your address or not. But in a townhouse or single-family home, it's less likely.
