While looking through the different types of posts, it got me thinking. The vf-0 was released with FP, so I wouldn't be surprised if the YF-19 was released with FP too (attached of course, the same way as the vf-0 ala magnets).
Now, what if Yamato was probably so impressed with the way the VF-0 was produced (CAD, magnets, other types of innovations) that they used what they learned from that, and applied it to the yf-19?...Alas, it's what lets me sleep at night while waiting for the YF-19...
