It's not about features, i believe i am not that advance user. It's just different from the RTOS i used to work on. Most of exist C RTOS work quite similar(FreeRTOS, Zephyr, ThreadX), the difference is mostly in API and Software support arround the core kernel.

But Embassy, with different task switching mechanism, mean i need to learn another new concept, understanding the pros/cons. That is not what i want to do when busy adapting to Rust.
