What I personally find more egregious are dotfiles and dot-dirs on Windows, created by half-baked ports of Unix-first software (such as `ssh`).
Windows has `%APPDATA%` and `%LOCALAPPDATA%` that are accessible with `ShGetKnownFolderPath`[0], using the appropriate `KNOWNFOLDERID`[1]; all programs should put their configuration and cache data in these paths.
Windows also doesn't know what the dot at the beginning of a file/folder means. Instead, it and NTFS have something that's arguably better: a hidden file attribute `FILE_ATTRIBUTE_HIDDEN`[2], that's again settable/gettable when a file/directory is created or polled, rather than regex-ing for a full-stop.
The worst irony is Microsoft software creating dot-files and dot-dirs on Windows[3][4][5].
