In this specific example there is a tremendous amount of large-engine experience wrapped up in the F1. These engineers are trying to learn from that to help design the next generation of big engines. Ignoring the work done on the F1 - failing to resurrect it - would force them to make the same expensive mistakes as their predecessors. And that, more than anything, will put a nail in progress's coffin.
Interesting to see what happens now that private enterprise is running its own programs alongside the government. I believe there will be a distinct chilling of relations between the main private players in a few years, once their main competition becomes each other rather than the government.
Anyway, I'd say researching a F1 engine is a great start point to progress towards the development of a newer rocket engine. Kudos to these guys!
