Eh, steel manning the role it kind of just sounds like a TPM. When roles are crisply defined, a good TPM has been a life changer for my job satisfaction. You basically get permission to farm out a lot of the most annoying parts of the job--status update forums, timeline management, and dependency wrangling--to another person who does it full time.
I've seen both versions of these. A good TPM is extremely valuable though, especially for work that is highly reliant on coordinating other teams. The bad version was a net negative to team productivity.
