I mean, I'm pretty sure it would be trivial to tell it to move files to the trash instead of deleting them. Honestly, I thought that on Windows and Mac, the default is to move files to the trash unless you explicitly say to permanently delete them.
Yes, it is (relatively, [1]) trivial. However, even though it is the shell default (Finder, Windows Explorer, whatever Linux file manager), it is not the operating system default. If you call unlink or DeleteFile or use a utility that does (like rm), the file isn’t going to trash.
