As there could be some users who still depends on the debugfs interface and forgot about the announcement, I just wanted to remind. DAMON user-space tool, damo[3], has supported both interfaces since the introduction of the sysfs interface and defaults to sysfs interface now, so the users of damo would have no problem. If you are still using the debugfs interface, you could refer to that to know how you could use sysfs instead. That said, there is no problem at extending the timeline if there is any critical user issue, of course. If you have such a critical issue, please let me know.
