Why does mui still use react prop-types library?

[heath-freenome]

Doing a source-graph search on "from 'prop-types'" that the library is imported almost 600 times. With React 19 removing propTypes support, I'm very curious whether the library will eventually stop using it? I am asking here because I couldn't figure out how to ask in the Discussions tab

@heath-freenome The main reason we are still using proptypes now is that the API docs on the site are (still) generated from the *.propTypes blocks in the components, so the biggest blocker for removing it is that the docs generation/infra will need to be reworked

Though even without the proptypes package, there are situations where having runtime type checking could be useful: #43138

@mj12albert Thanks for the response. Good luck finding a doc generation solution that works as well, if not better than a prop-types one
