I've just written the code for NetSurf for WebP too, so at least one web browser will shortly be supporting it.
It's nice to have other browsers than just WebKit based ones supporting it.
"While WebP images can’t be viewed until browsers support the format, we are developing a patch for WebKit to provide native support for WebP in an upcoming release of Google Chrome."
It takes a long time for a new graphics format to gain a following, I was using PNG for years (on my website too) before the main browsers started supporting it properly, and got lamented for it. Now everybody uses PNG. You have to start somewhere. I'd rather release this now and show that AmigaOS is still up-to-date, than wait five years for the forums to be full of "why can't I view this image, it's in WebP format?".
WebP is still evolving as far as I can tell, so I think I'll rather wait and see if any need for it will arise before bothering too much with it.
Then again I'd indeed be just 30 mins of work to get it going as datatype... so why not.
As for being up-to-date, there are still some very basic core features missing/incomplete in the OS4. As long as you're not able to use basic things such as USB2 or flash it's quite hard to appear modern. 3D support is quite poor, too.
