I discovered this a few days ago (https://news.ycombinator.com/item?id=11152640 https://news.ycombinator.com/item?id=11152640) on my Kindle Fire HD 6. I ran it quite happily with encryption under Fire OS 4, and upgrading actually required that I wipe the device. Amazingly, Fire OS 5 (without encryption) appears to run about the same, or maybe even a bit more slowly. The HD 6 actually has decent specs, so I'm speculating that this is mainly to improve performance on the newer $50 tablets that don't have the computational power of the older models.
