Slashes are used in paths, so most programs that aren’t Mac-exclusive would use them to build a path to file. To make it work properly in cross-platform programs you’d need to write platform-specific code to handle that. It just adds complexity and possible errors. Even system terminal doesn’t display it as slash and it doesn’t work if you write slashes.

For users of other platforms (at least 90% of desktop market) it would just display as slashes. Just not implementing this workaround would make it predictable when moving and using files.
