How do you think optical image stabilisation works?

And also focusing. We already have phones with lens elements moving around on multiple axes.

I had no idea. My idiot self thought it was all software in phones. Time to do some reading!

You’re not entirely wrong, both of those features have been specifically called out as sensitive to vibrations and more prone to failure. Some lenses, such as front-facing camera on most laptops and older iPhones, are fixed lenses that don’t move at all — so yes some of them work that way!

Well color me stupid because I thought that was only through software in phones. Time to do some learning!

That's electronic image stabilization, often used in conjunction with optical stabilization.
Some phones can actively move the OIS hardware to get a desired effect, like shifting the sensor to get more detail out of image stacking
