I’ve been using bc7 since 2012, and even have a video codec using bc7 keyframes (we needed alpha videos, even have a patent for it). Our emphasis is not file size, but playback speed. Bc7 renders 20-40% faster than raw rgba32, and we overlay 5-7 videos on screen simultanously, so every boost helps.

We also have custom encoders for the custom video format.

You have a patent for alpha in videos? Curious to hear more about this - the application you describe sounds eerily familiar to me.
