/**
 * Warns about reliance on a React 18 compatibility shim that emulates an API
 * removed in React 19. Each distinct `key` warns at most once, so repeated use
 * of the same shim does not flood the console.
 *
 * @param {string} key     Unique identifier for the compatibility warning.
 * @param {string} message Human-readable warning message.
