Nothing wrong with the format in particular. However some may prefer formats such as PNG and JPEG since:

* A lot more software supports PNG and JPEG (backwards compatibility, better integration with one's existing system and tools).

* You can often get the same file size, visual quality, and performance with PNG and JPEG as you can with WEBP with optimization.

Interesting concept but find this one promoting going backwards. I understand people like rotary phones.
