Not entirely true for O scale. I have seen these DCC controlled KD couplers and actually own a few pair. I have not installed them yet, but may soon. They are fully DCC controlled.

Also there is another company making HO scale DCC controlled couplers that don't look as bulky. Reading further on their website, this company is developing for O scale also. https://www.smart-coupler.com/home-eng
