Shutil was among the most important to be updated, IMO. I had made some sort of list of affected modules elsewhere [1]: ntpath, posixpath, os.scandir, os.[other stuff], DirEntry (tempted to say os.DirEntry, but that is not true), shutil.[stuff], (io.)open, fileinput, filecmp, zipfile, tarfile, tempfile (for the 'dir' keyword arguments), maybe even glob and fnmatch (are the patterns paths?) It looks like what made it to PEP519 was mainly this: "It is expected that most APIs in Python's standard library that currently accept a file system path will be updated appropriately to accept path objects (whether that requires code or simply an update to documentation will vary)." > Was shutil updated at all?

If so, it is an enhancement. Regardless of bugfix vs enhancement semantics, that seems like a good thing to do. -- Koos [1] e.g. in this thread somewhere: https://mail.python.org/pipermail/python-ideas/2016-April/039827.html -- + Koos Zevenhoven + http://twitter.com/k7hoven +
