Has this happened yet?
Is this in v3 of the RTOS sdk?
Will the RTOS sdk eventually be rolled into an ESP-IDF specifically for the esp8266?
Although I don't use the RTOS SDK, I am planningwork with esp32 ESP-IDF so knowing the answers to this will help me plan better and help porting/migration of any esp8266 code.
I know that these are questions for Espressif but I imagined a better response if I asked here, so hope you don't mind!
