I can think of lots, though I don't know that I've used any in my
existing (somewhat limited) code that uses Path, but they all involve
cases where I would expect, if comparisons were disallowed, to just wrap
the string in a Path first, even though to me that seems like it should
be an unnecessary step:
if mypath.splitpath()[0] == 'c:/temp':
if 'tests' in mypath.dirs():
and lots of other uses which start by treating a Path as a string
first, such as by doing .endswith('_unit.py')
Any of these could be resolved by ensuring both are Paths, but then I'm
not sure there's much justification left for using a baseclass of
basestring in the first place:
if mypath.splitpath()[0] == Path('c:/temp'):
if Path('tests') in mypath.dirs():
Question: would this latter one actually work? Would this check items
in the list using comparison or identity? Identity would simply be
wrong here.

Fair enough, though in either case an attempt to access that information
leads to the same exception. I can't make a strong argument in favour
of properties (nor against them, really).

As John Roth suggests, the former seems a much more useful thing to do.
The latter is probably as rarely needed as it is with regular strings
(which I believe is roughly "never" in Python).

Point taken. What about ditching the "file" part, since it is redundant
and obvious that a file is in fact what is being accessed. Thus:
.read_bytes(), .read_text(), .write_lines() etc.
