Any recent experiences of requesting an Early reset? Specifically, do they still do it and, if so, how long does it take for them to reset the membership year?

Have flights early December that get me to the Club Points I want to have, in this year. Have another set of flights end-December that I want to bank in the next membership year. While removing the frequent flier number (& claiming in 2024) is an option, I won't mind having the status linked higher lounge access.
