Nope - do your research better before you use the word "lie". BAYC did it until very very recently for instance. Definitely as of 27th September they were using cloud functions as you can clearly see in my gist here: https://gist.github.com/JofArnold/bf2c4a094fcdd4aee2f52983c7... I know there is/was plenty of others too because I looked deeply into this around the time.
