Also to add to your point, file storage is becoming ambiguous with cloud option and also very cheap and abundant on most devices these days, internet speed is fast enough that large file size is not that big of an issue, so the benefits outweigh its limitations. GIFs are still best way to quickly share something that is expressive and purely visual. There are other technologies to support looping visual, but nothing that has been universally supported as GIF has. I'll be happy to offer other formats once they become available in the future.
