Ok, but like, how often is she actually going to use these animations and toggles? That's the kicker that always comes to mind for me. People spending thousands on a cutting edge model only to spend all their time with the same chest-up view and few generic expressions. Like Shylily said in that clip, most vtubers could do with learning how to actually pilot a model and act/emote properly and save a lot of money in the process.
Why learn to act when you can pay exorbitant fees (priced at exploitative rates intentionally!) to attain a button that will "act" for you, only for you to forget to press it 10 out of 10 times when it would be needed?
