Understood, however the userbase of RELENG_8 is significantly higher
than that of HEAD/CURRENT, and the userbase of RELENG_8 is a lot more
likely to complain en masse when something breaks.
My goal was to bring to the attention of the community that a large
number of storage/AHCI/SATA-related MFCs had been done, and request that
people (if possible) rebuild world/kernel to make sure all of their
stuff still works.
Better to catch it during RELENG_8 than during RELENG_8_3. :-)

I also did the same on mine.
