This is already the case with different image compression algorithms improving on one another. Users couldn't and shouldn't tell the difference between JPG, or slightly smaller / resized JPG, or WebP, or whatever. I personally don't think image hosts should have to alert users when making undetectable changes to their images like this.

I'm sorry, but JPEG compression is extremely noticable especially with non-photographic material such as web graphics. The compression is lossy by nature, and predictably introduces noticeable artifacts. WebP on the other hand has support for lossless encoding.

It's simply not the same thing. If I opened my file browser one day and saw that all of my FLACs had been converted to MP3, I would go on a murder spree.
