Fully general re-dispatch from argument types on any call to a function

Have pathlib monkey-patch things at import?
Implicit conversion. No, thanks.

So, I might add:
3. add more high-level features to pathlib to prevent a downgrade to os

What's the point of batteries being included if you can't wire them to
anything?
Huh? That makes not sense to me.
I don't get what you mean by this whole "different level of abstraction"
thing, anyway.
Strings are strings. Paths are paths. That's were the difference is.
The fact that there is one obvious thing to want to do
with open and a Path strongly suggests that that should be able to be
done by passing the Path to open.
Path(...).open() is your friend then. I don't see why you need os.open.
Refusing to upgrade it like saying, everything was better in the old
days. So let's use os.open instead of Path(...).open().
Also, what level of abstraction is builtin open? Maybe we should _just_
leave os alone on the grounds of some holy sacred lowest-level-itude,
but allow io and shutils to accept Path?
os, io and shutils accept strings. Not Path objects. Why? Because the
semantics of "being a path" are applied implicitly by those modules. You
are free to use a random string as a path and later as the name of your
pet. Semantics of a string comes from usage. Path objects however have
built-in semantics.
Furthermore, if os, io and shutils are changed, we allow code like the
following:
my_path.touch()
os.remove(my_path)
I don't know how to explain reasonably why my_path sometimes stays in
front of the method call and sometimes behind it to newbies.
Best,
Sven
