My take on where it should be exposed.

Something related to the battery, which are charge thresholds, are supported in
multiple laptop brands (Lenovo ThinkPad, ASUS, System76...) and are thus are
exposed in the battery power supply device
(/sys/class/power_supply/BAT0/charge_control_{start,end}_threshold)

conservation_mode is basically an equivalent with a fixed value (60%) that is
exclusive to IdeaPads, and it's exposed in the platform device
(/sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode).

I guess that my the verdict is that, because rapid charging is supported on
multiple laptop series (both ThinkPads and IdeaPads, which use different
drivers, and maybe there are more brands, though I couldn't find anything on
Google), so it should be exposed in the battery power supply device.
