Is the ESP8266 still supported, is there still a need to maintain backward compatibility?

Looking at the code, it seems that it still supports the ESP8266. However, I don’t remember where I read that only the ESP32 is supported. Can someone clarify which devices are actually supported?

This is because I’m having serious problems with log management on ESP8266, which supports the F() macro differently from ESP32, and before I go mad, I’d like to understand whether it makes sense to invest this time.

Yes code supports ESP8266, we removed the support of HM10 for BLE a few years ago but for the main part of the other modules we still support ESP8266
