File extensions are a kludge anyway. (And Windows 10 still hides them by default, because hey, backwards compatibility, and you wouldn't want to confuse Grandma who's seen the file be called "grandkids" since Windows 95..).
Why should the filetype be dependent on the name? People even think renaming a .BMP to .JPG means now it's a compressed file!
Old school Macs stored the filetype outside of a file, so you can rename the file "grandkids.mp4" and double-clicking it would still open it in the image viewer.
