sure to read the documentation string to make sure.

Not every function provided in newer versions of Emacs is provided
here.  Some depend on new features from the core, others cannot be
implemented to a meaningful degree.  The main audience for this
library are not regular users, but package maintainers.  Therefore
commands and user options are usually not implemented here.")
