The request to "add sensor type tags to components (temperature, humidity, etc.)" is already addressed in the esp-iot-solution ecosystem through the Sensor Hub component, which provides a hardware abstraction layer with sensor type classification.

How Sensor Types Are Already Handled

The sensor_hub component defines a sensor_type_t enumeration that categorizes sensors: [Sensor Hub API]

• HUMITURE_ID — humidity or temperature sensors
• IMU_ID — gyro or accelerometer sensors
• LIGHT_SENSOR_ID — light/UV/color sensors

Sensor data is carried in a sensor_data_t struct that includes typed fields such as temperature, humidity, baro, light, etc., along with a sensor_type field. [Sensor Hub API]

Registering a Sensor with a Type Tag

Driver developers register their sensor under the appropriate type using the SENSOR_HUB_DETECT_FN macro. For example, the SHT3X temperature/humidity sensor is registered under HUMITURE_ID: [Sensor Hub]

static humiture_impl_t sht3x_impl = {
    .init = humiture_sht3x_init,
    .deinit = humiture_sht3x_deinit,
    .test = humiture_sht3x_test,
    .acquire_humidity = humiture_sht3x_acquire_humidity,
    .acquire_temperature = humiture_sht3x_acquire_temperature,
};

SENSOR_HUB_DETECT_FN(HUMITURE_ID, sht3x, &sht3x_impl);

Currently Supported Sensors by Type

Type	Supported Sensors
Humiture (temp/humidity)	HTS221, SHT3X
Light Sensor	BH1750, VEML6040, VEML6075
IMU	LIS2DH12, MPU6050
Gas	BME690

[Sensors readme]

If the issue is requesting that additional components (e.g., AHT20, HDC2010, BME280) be tagged and registered under the appropriate sensor types in the Sensor Hub, the pattern above (implementing the relevant _impl_t struct and calling SENSOR_HUB_DETECT_FN) is the established way to do so. You may want to reference the existing SHT3X driver as a template for contributing new sensor drivers.
