This is part of #5153 but is being prioritised because we want remove the declareLegacyNamespace calls from the core/utils/*.js modules and then reexport them explicitly via utils.js, and it turns out that doing so results in the exports object of this module being passed to Object.freeze - which fails on the global object, which can't be made non-extensible! The new name chosen for the former default export is globalThis, since it is intended to have the same value as the global variable of that name; see: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis
