Comment (by desrosj):

 In [changeset:"54816" 54816]:
 {{{
 #!CommitTicketReference repository="" revision="54816"
 Filesystem: Return FTP/FTP Sockets `exists()` methods to a previous state.

 This partially reverts [53860] and [53862], which refactored the
 `exists()` method to rely on `ftp_rawlist()` instead of `ftp_nlist()`.

 [53860] makes a similar attempt to the ones made in [33648] and [34733]
 (which were also reverted in [35944]). Being compliant with the
 specifications while continuing to work without issue for all FTP servers
 continues seem impossible. These little ghosts are the ones we’re scared
 of the most.

 Props jsh4, afragen, costdev, pkolenbr, SergeyBiryukov, dd32,
 peterwilsoncc, gamecreature, desrosj.
 Merges [54815] to the 6.1 branch.
 Fixes #56966.
 See #51170, #28013.
