Thanks for posting this, Chris. I begin to wonder if the amazing observations of no distortion on lens like the xf14 (assumed to be the result of great optical design) are false.

According to Photozone's tests of the 14/2.8 XF lens:

"The produced distortion of the Fujinon is possibly the biggest surprise in this review - it has almost none (0.4% barrel distortion). This is also valid for the RAW data so there's no active auto-correction necessary here."

For raw files, the optical correction parameter estimates computed by Fujifilm's R&D staff are transferred from the on-board lens firmware to the raw file. Third-party raw rendering software applies these corrections during rendering. Some programs (Adobe) automatically apply the corrections no matter what, others let you decide and and a few ignore them altogether.

They might have a assumed raw would not contain the corrections, as we are finding out it does...so I guess it depends on what raw converter Photozone used and how it was set. Maybe they were fooled by this?
