Small bug report encompassing some related issues in `pathlib._NormalAccessor`:

- `link_to()` should be named `link()` for consistency with other methods
- `symlink()` doesn't need to guard against `os.symlink()` not accepting `target_is_directory` on non-Windows platforms; this has been fixed since 3.3
- `readlink()` doesn't raise `NotImplementedError` when `os.readlink()` is unavailable

Only the last of these has a user impact, and only on exotic systems.

I don't think rename 'link_to'  to 'link' directly is a good idea. Because there are many third-party libs have used this name. Unless we can keep two names in this version, and remind people the 'link_to' function will be deprecated totally in a future version. But is there any way to make a function as deprecated?

About 'os.readlink', we can hide this function in the platform that doesn't support readlink() just like `epoll' in mac or etc.

But when will os.readlink() be unavailable?

Fine, I get your means

Good points! Do you know of an example of a community library that uses ``? Thanks
