  "issue": "FTPFS should use MDTM\nRegarding fs.ftpfs.FS.getinfo (https://github.com/PyFilesystem/pyfilesystem2/blob/64d7a52e1f3037f33937f91e9db812cafdbbafc0/fs/ftpfs.py#L648)\r\n\r\nThat function tries to use MLST to retrieve arbitrary information of a single file and defaults to LIST if MLST is not supported. \r\nThis makes `fs.copy_dir_if_newer` incredibly inefficient on systems that do not support MLST. \r\n\r\nImo, an easy solution would be to possibly support MDTM as a fallback if only the modified datetime is requested, e.g. if `namespace == (\"detail\", \"modified\")`.\r\nAnother, probably more complex improvement, would be to cache the LIST response rather than call it for every single file.\r\n\r\nI can submit a PR for the first suggestion, if I get the okay that this is something that should be included. Possibly also the second, although I'm not sure yet how to best implement that.",
