Description

We are currently on mui v4 / jss and have been looking at upgrade path for a while.

Our expectation was to switch to mui v6/7 which supports new runtime-free css engine - but looks like mui7 out last week is still sticking with emotion.

The whole pigment css saga has been disappointing. When this was announced over an year ago, there were many asking the need for a separate styling lib instead of adopting stylex / griffel (developing a new styling solution is really hard) but there were apparent benefits with the proposed solution.

Now since 1 year of announcement, there is no proper release / upgrade path yet for pigment and looks like it is undergoing major refactor for v1?

Meanwhile, Base UI, which got release, while impressive, doesn't even mention Pigment CSS.

There is not even a website since an year this was announced, where an llm can generate one in 10 mins these days.

In this day of React 19 + RSCs + Shadcn + Tailwind, does the team still expect pigment css to be THE future at MUI?
