Comment (by schlessera):

 @jrf Yes, of course, the functionality proposed here can and should
 already go in with a next minor release. I just thought your proposed
 polyfills demonstrate the growing need for a more systematic approach,
 that's why I linked.

 Using functions like the above makes the code more future-proof and less
 error-prone, so there's no reason not to add this small polyfill.
