Feature or enhancement

It was deprecated in 3.13:

* :mod:`pathlib`:

  * Deprecate :meth:`.PurePath.is_reserved`,
    to be removed in Python 3.15.
    Use :func:`os.path.isreserved` to detect reserved paths on Windows.
    (Contributed by Barney Gale in :gh:`88569`.)

cpython/Lib/pathlib/__init__.py

Lines 521 to 531 in 9b9cdb6

	def is_reserved(self):
	"""Return True if the path contains one of the special names reserved
	by the system, if any."""
	import warnings
	msg = ("pathlib.PurePath.is_reserved() is deprecated and scheduled "
	"for removal in Python 3.15. Use os.path.isreserved() to "
	"detect reserved paths on Windows.")
	warnings._deprecated("pathlib.PurePath.is_reserved", msg, remove=(3, 15))
	if self.parser is ntpath:
	return self.parser.isreserved(self)
	return False

I have a PR ready.
