It's time to make some difficult decisions about which methods deserve to stay in the pathlib._abc.PathBase interface, and which ought to be made pathlib.Path-only. Guidelines:

• Compare to zipfile.Path and os.DirEntry; don't evict shared methods.
• Include abstract methods only for the most basic functionality common to all virtual filesystems
• Include concrete methods only when they combine abstract methods to produce widely useful functionality
