How many bolts are you going to put in to make it "safe"? It's a trad line, and properly so. Lots of features. Easy to build gear anchors. Ledges. Sitting belays. Low-angle.
This may be a "high-traffic newbie area" but it is still a multipitch trad line. It's climbed by beginner multipitch trad climbers, to learn beginning multipitch trad. You shouldn't climb R&D if you don't know how to place trad gear. You shouldn't go on this route if you don't know how to build a gear anchor. You shouldn't go on multipitch routes if you don't know self-rescue. This is a case-in-point.
I still don't understand your reasoning and don't think you've explained it very well. For adding bolts to an easily-protectable trad route, if the best argument you can come up with is "what could it hurt", then, I think no. No bolts.
