I've looked at the underlying code for 1.16.5 and 1.17.1 using the Forge workspace, and I can confirm that the leak still exists, as the FriendlyByteBuf (and the underlying ByteBuf) for the S->C custom payload packet is still not released properly. For reference, I've opened PR #8042 at Forge which patches this.
