…R.TAG This helps to prevent bloating backups with unwanted (possibly frequently changing, if __pycache__ directories are removed and recreated) files. Granted, one can add __pycache__ directory to their backup-tool-of-choice exclusion list, but those lists are ever growing and maybe it'd be good to help the tools and the users. See https://bford.info/cachedir/ for more information about the specification – it's supported by Borg, restic, GNU Tar and attic out of the box, other pieces of software (like rsync, Bacula and rdiff-backup) can be made to use it (partially, just the existence of the tag file is used, not its content)
