Let's update the link on https://mui.com/base/react-input/#multiline to point to this new page.

Should we link the components which are basically duplicated in both base and Material UI by adding an unstyled section on the Material UI page?

We can explain that the @mui/material instance is just a re-export and the component lives inside the Base package. Perhaps someone may find it useful if they intend to use the library for just the utilities (so they can import from Base instead).

Exactly, let's do it! It probably should be enough to just link the unstyled page, as done in the modal - https://mui.com/components/modal/#unstyled

It's a bit different in this case as we don't have an unstyled version of TextareaAutosize. It's exactly the same thing. I emphasized this in the description. Please let me know if you find it better.

Looks great
