I've yet to meet a manager whose only job isn't a futile attempt to make themselves relevant to the process.

Only useful managers are those who are actually performing a dual-role as some sort of social lubricant for the team. You could just replace that manager role with a social engineer whose responsibility is to further psychological safety for everyone, and drop the pretense that they know anything about technology or manage what everyone should do.

I have seen managers who were very effective at their work. But they actually understood the software in depth and were very skilled at shielding the team from politics.
