[issue38222] pathlib Path objects should support __format__

[Serhiy Storchaka]

I am -0 on this. It is a can of worms. Once we add a trivial __format__ in Path, we will need to handle numerous requests for adding a trivial __format__ in many other classes. It is better to teach users to use !s (and this works also on older Python versions!).

As for Path, there many ways to convert it to string: str(), repr(), os.fspath(), os.fsdecode(), Path.as_posix(), Path.as_uri(), with possible normalization, converting to absolute or relative path. I would not bet that we will never have reasons to have a different format specifier language for Path.
