For BPF CORE we have 4 maintainers and 7 official reviewers. bpf mailing list receives ~70 emails a day. bpf development can scale only when people who actively develop are also actively reviewing code. M and R entries in MAINTAINERS file is a recognition of the prior efforts. Not much more. We need to trim it and remove people who are no longer active.
