cc #4818 (comment)

1. I guess this doesn't make sense to change as it already has requirements which have to be checked:

   esp-hal/esp-radio/src/ble/os_adapter_esp32c3_s3.rs

   Lines 411 to 414 in f45fcc7

   	/// Scan duplicate filtering list refresh period in seconds.
   	///
   	/// Range: 0 - 1000 seconds
   	scan_duplicate_refresh_period: u16,

2. EspNowManager and EspNow:

   esp-hal/esp-radio/src/esp_now/mod.rs

   Lines 517 to 520 in 2be0272

   	#[instability::unstable]
   	pub fn set_wake_window(&self, wake_window: u16) -> Result<(), EspNowError> {
   	check_error!({ esp_now_set_wake_window(wake_window) })
   	}

3. WifiCsiInfo:

   esp-hal/esp-radio/src/wifi/csi.rs

   Lines 135 to 139 in 2be0272

   	/// The local time in microseconds when this packet is received. It is precise only if modem
   	/// sleep or light sleep is not enabled.
   	pub fn timestamp(&self) -> u32 {
   	unsafe { (*self.inner).rx_ctrl.timestamp() as u32 }
   	}

4. FineTimingMeasurementReportEntry has a bunch of functions:

   esp-hal/esp-radio/src/wifi/event.rs

   Lines 391 to 394 in 2be0272

   	/// Gets the Round Trip Time (RTT) in picoseconds.
   	pub fn rtt(&self) -> u32 {
   	self.0.rtt
   	}

   
   but this is in picoseconds and I'm afraid that using micros and math will ruin the recision here

5. FineTimingMeasurementReport same as 4 but nanosecond:

   esp-hal/esp-radio/src/wifi/event.rs

   Lines 428 to 431 in 2be0272

   	/// Get the raw round-trip time (RTT) in nanoseconds.
   	pub fn rtt_raw(&self) -> u32 {
   	self.0.rtt_raw
   	}

I hope I didn't miss any other pub appearance. I think it doesn't make too much sense to do that for NON-pub API.
