Not all flag names were updated to match updates to Tasmota source in `support_features.ino`. I assume the changes to be uncontroversial, with the possible exception of:
While `USE_TUYA_DIMMER` arguably is a more descriptive name than `USE_TUYA_MCU` the former name is not found anywhere in Tasmota code, which has
```
#if defined(USE_LIGHT) && defined(USE_TUYA_MCU)
feature2 |= 0x00008000; // xdrv_16_tuyadimmer.ino
#endif
```
My assumption is that the actually used names "wins", to avoid user confusion, even if you could say that the name `USE_TUYA_MCU` is too broad for the actual feature. In principle, it would be more logical to create a new "real" `#define` name, but backwards compatibility and all that.... Makes sense?
I'm ok either way....
