Way too early to tell if the new RP Street oils without the Synerlac are not as good as they used to be. In an older vehicle that needs ZDDP that would ring true. However, in a modern vehicle where it is not required it may not be true. I would wager that the new RP street oils are pretty darn good all the same.
I have a 2011 Jeep too( Patriot )and I am running the RP 5W20 as well( the street stuff rated API SN )and an RP filter. I am happy with it so far. I also go with 5K OCI's during warranty. Easier for me to remember 5K intervals plus that is when I rotate the tires. Works out well for me.
Is it overkill? Sure as it would be with most any synthetic. Do I care? Not in the least.
