// For the core and vendor variant, the "backup" instance points to healthd,
// which is removed.
// For the recovery variant, the "backup" instance has a different
// meaning. It points to android.hardware.health@2.0-impl-default.recovery
// which was assumed by OEMs to be always installed when a
// vendor-specific libhealthd is not necessary. Hence, its behavior
// is kept. See health/2.0/README.md.
// android.hardware.health@2.0-impl-default.recovery, and subsequently the
// special handling of recovery mode below, can be removed once health@2.1
// is the minimum required version (i.e. compatibility matrix level 5 is the
// minimum supported level). Health 2.1 requires OEMs to install the
// implementation to the recovery partition when it is necessary (i.e. on
// non-A/B devices, where IsBatteryOk() is needed in recovery).
