I believe it's the latter; since in older API versions if you did any update to the subscription and that update did not also remember to re-pass cancel_at_period_end, it would clear the cancellation

easy enough to test in test mode though!

I did a quick test just now (create subscription, update to set cancel_at_period_end, update a few seconds later to set some metadata) and the canceled_at updated to the time of the most recent request
