[RFC] Remove enableColorScheme prop from CssBaseline

[o-alexandrov]

What's the problem?

There is an unused prop enableColorScheme in CssBaseline which gives an option to choose something that does not make any sense.

From #42640 (comment)

What’s the need for enableColorScheme: false?
In other words, why would anyone want the browser to show light color scheme for a dark theme?

The existence of enableColorScheme led to the introduction of an extra hanging span HTML element.

What are the requirements?

Remove enableColorScheme prop

What are our options?

In Material UI v7+, you might consider to remove the enableColorScheme prop.

The prop was added to avoid breaking changes, as far as I remember.

This issue looks like point 4 of #38507 but where we also remove the prop.

[o-alexandrov]

@oliviertassinari thank you for linking the issue and specifying the point 4. Would you like to reword the 4th point there, so it says removal, instead of setting the value to true by default?

• if yes, then I’d happily suggest to close this issue as this one would become a duplicate

I think we can remove it before the stable release of v6. It's a breaking change but I think CssBaseline is used once in a project.
