Yes, you are right, I really love to hear that. But as a webdeveloper my first task after I write some code is to test it in a webkit browser. Webkit is everywhere iPad, iPhone, Chrome, Safari, ( now Opera ). I think bad developers will start to exclude other engines support if percentage of non-webkit browsers goes very low. And since a lot of websites are coded from amateurs ( there's nothing wrong to this ) there will be more and more webkit-optimized content. That's sad!

It's not just amateurs.

The "mobile" sites out there are overwhelmingly WebKit-only. We're talking sites from Google, Disney, Apple, various news sites, etc, not sites done by amateurs.

And they're not accidentally WebKit-only in many cases, but deliberately so.

>> I think bad developers will start to exclude other engines support if percentage of non-webkit browsers goes very low.

Bad developers are already ignoring everything except whatever single browser they [might have] tested in.

This move certainly is unsettling, but I think you can come up with a better argument about why.

Note that there's some fragmentation in WebKit as well. I think that developers that assume it will make their lives a lot easier will be slightly disappointed in the end.
