Seems like a deprecation. If you want to work on a PR to change it to the new way to do it, you are more than welcome.

The deprecation warning is for React 19. React 19 is currently in beta. It is expected to be out of beta in June or July 2024.
So, the person working on the PR could a) Ensure it works without defaultProps in React 18 and b) Use React 19 Beta to test compatibility.
