Obviously, there is no right answer here, but too many feeders seems like an unnecessary waste of time, effort, and money to me.
This has kind of swerved away from the original thread topic, but one reason is that soldered feeders are more reliable than mechanical rail joiners. A bad joint, or one that gets corroded over time, can cause a large section of dead rail. Additional power feeders insure against electrical reliability and maintenance issues.
