Can someone help me understand DevKit naming conventions?

[qubdtq]

This page seems to be an overview of the ESP32-DevKitC family of products, but the list seems to be of many products that, as far as I can tell (I'm a total beginner) have nothing to do with DevKitC... am I correct? E.g. ESP32-S2-DevKitM-1, ESP32-S3-Korvo-1, all the S series and C series, etc.

Also, there are many products with names like:

ESP32-S2-DevKitC-1
ESP32-S3-DevKitC-1
ESP8684-DevKitC-02
ESP32-C3-DevKitC-02
ESP32-C6-DevKitC-1
ESP8266-DevKitC

...are those products in the DevKitC family or do they just have confusing names? If they are in the DevKitC family, why are they not shown on this other DevKitC summary page?

Thanks!
