"Modern Standby" requires that power draw (and thus thermals) is comparable or lower to S3.
It's less about telemetry etc. (you could do it with age old ACPI timers), it's about people complaining laptop doesn't boot immediately from sleep when they open the lid - but also that on a system where power management support is heavily tested (read: not Linux) "Modern Standby" has less moving parts and is harder to break.
