The only reason why that makes any sense is it is just easier for the creator only having to change one file instead of three.
好吧，不过我还是觉得有必要隔离不同版本，让用户自由选择不同版本下载，虽然不知道创作者的操作终端是什么样的。
While I agree it should be separate files, it is up to the creator if they want to make things convenient for themself or the rest of the internet.
