No, I don't think that's the reason. I think the reason the system has been graded as mediocre is the lack of high-end talent... which is natural. After a team graduates the likes of Rosario, Sano, Berrios, Buxton, Kepler, et al in a time span of 28-ish months, coming away from that with a "mediocre" farm system is something of an accomplishment. What we're seeing now is the emergence of a new crop of talent, which is going to bump the farm system back up a few notches. Seeing players like Gonsalves, Romero, Gordon, and Thorpe begin to come into their own suddenly makes the system look a fair amount better.
