Now, when stable/14 is almost in sync with main aka CURRENT it's an optimal time for such a MFC.

From now on stable/14 and in the future on 14.1-RELEASE one will be able to load tcp_rack and tcp_bbr out of the box running GENERIC kernel.[1] 1. https://cgit.freebsd.org/src/commit/?id=123fd2a -- Marek Zarychta
