While better than armorstands pre 1.19.4, display entities still require a price of performance on the client. For lesser able systems this might prove taxing.
A option to use standard blocks instead of display entities would be a great option to have, it would make the animation less smooth due to having less places. But it would allow for players with older machines to handle them much better.
I currently have no plans for a feature like this. I might add a feature to disable animated blocks per-player, but I'm not sure when/how/if I will implement that.
