4. WebKit and Chromium have historically had differing opinions regarding what makes a "good" comment. I think you can expect Blink's code to tend more and more towards Chromium-style as time goes on, but it's not going to happen overnight.
5. ~5 million lines of code that we don't currently compile or run in Chromium. That's a bit, but it won't have much effect on the binary size.
6. Short term, not much will change. Longer term, a few things will probably happen: for instance, the widget tree will likely be removed, and we'll likely be able to step back and reevaluate some changes in light of that.
I mentioned above that the last time I measured (late 2012) the entire mozilla-central repository it was 4.488 million lines of code. How many lines is Chromium? How on earth can you be removing 5 million LOC?
2. I'm not sure what you mean.
3. We can't, and don't want to, change the license of code that's already been released. That said, most (all?) of WebCore isn't LGPL. See my favourite file, http://trac.webkit.org/browser/trunk/Source/WebCore/page/Con... for example.
