BEP46 aka Dynamic Content Updates and Decentralization is, if I recall correctly, rolled into BEP-52 , aka The BitTorrent Protocol Specification v2 which has been the standard since 2020 (or so) and on paper since 2017 (ish).
( again, IIRC )
Question is, of course, how many release groups, public and private trackers are supporting this feature?
