[oliviertassinari]

• I have searched the issues of this repository and believe that this is not a duplicate.

Summary 💡

In the v5 RFC issue, we have a mention of doing this change but no dedicated issue. Developers can get a better idea of the motivation for the change by searching for getOptionSelected in the closed issues. Or #19595 (comment)

Motivation

Make the API more intuitive, the mental model can be improved.

On a related note, a few developers have been asking for the same feature with the Select: #24201

Would recommend using optionEqualsValue or isOptionEqualToValue to use natural language (just like React has arePropsEqual).

@mbrookes a preference?

I'd say most fields on the autocomplete would benefit from a rename. It's really hard to tell what the role of anything is just by looking at the name. I even had to dive into source to understand the relationship between PaperComponent and ListBoxComponent.
