How is cloud based image hosting going to solve the lack of WebP support in Bootstrap Studio?
People need to understand that Google has a vested interest in making everything on the web as small, compressed and fast as it can be, regardless of whether it's best for users, because it saves them throughput which reduces their search costs. Ten years ago they bought the company that came up with the WebP compression algorithm, so naturally they'd love to see it embraced so their investment pays off. They implemented WebP across YouTube for all their thumbnails and saved a whopping 10%. Significant when you're YouTube with millions of thumbnails. Trivial for most other people.
Next problem: while WebP does, in many (but not all) cases result in slightly smaller image sizes with little to no compromise in quality, it still lacks universal support (even after being around for almost ten years.) And this assumes you're starting with uncompressed, raw image files and converting to a compressed format. Going from .jpg to WebP is a dicey affair. Furthemore, when dealing with alpha channels (24bit PNGs) WebP images are always larger.
Third problem: WebP images are kinda useless when it comes to sharing. You can't easily view them in native Windows apps, you can't edit them in Photoshop (without a plug-in), and you can't send them to your friends with Apple products.
So it boils down to costs vs benefits. Do your really want to code jpg fallbacks for all your WebP images for the Apple and IE crowd just to enjoy a small amount of data savings for Chrome and Firefox users on certain larger images (assuming your site has lots of large photos and is not specifically a photography site (in which you'd generally stay away from any compressed format for your images.)
IMO, lazy loading is a simpler solution.
After ten years, if the format had merit, it would have already been adopted universally.
