Well at least that (2023 version) explains it.
To address OP "why the devs decided to have utility tracks?"
Well, short answer, it's better to have them than not. I believe you still can (in 2023) use node volume automation to mute/unmute tracks at particular bars.
Better yet, support progress of a smaller company and get the updates which includes the mutes for Utility tracks at F5 and much more. You are on patch 1010, current is 1128.
