- "Files" (paths) that support PROPFIND vs. not
     - (HTTP error code if verb not supported?).
- Is HEAD still necessary if PROPFIND is supported?
- Affected methods on SshFile:
     - listSshFiles()
     - isFile()
     - isDirectory()
     - getSize()
     - getLastModified()
     - doesExist()
     - These are indirectly affected:
          - isExecutable() (through isDirectory())
- Which methods require lazy loading considerations (listSshFiles()).
