What is lost?
- sanity checks and redzoning on all devices
- redzoning reportedly however causes issues on some devices such as the Pixel 3/4 and OnePlus 7
- slub sanization on 3.0, 3.4, 4.4 (except google/wahoo), xiaomi/sm6150, and oneplus/sm7250
Note: all 3.4+ devices still have page sanization

Change the property too, so it takes effect next update.
Since 16.0 lacks a toggle, this effectively disables the feature for it.
Even devices with 4GB of RAM have usability severely impacted.
Plus some other tweaks/churn
