What's the plan when these are enabled by default?  Would the embedder need to
try setting it and then poll?  Maybe it should return a boolean for whether or
not it was successfully set?

[darin (slow to review), 2009/10/30 06:38:25]

I just did what you suggested earlier.  The embedder always calls enableFoo with
the value it wants.  So, the defaults don't matter.

However, if we want to remove the code that calls enableFoo, then
we would probably do that once we know for sure that the feature is
enabled by default, or we would just always have code to call enableFoo(true).

The defaults do matter when the embedder doesn't call enableBar, which might
happen when you mix an old Chrome with a newer WebKit.  I'm okay with the
default floating like that.

[jorlow, 2009/10/30 07:08:02]

I imagined that the WebCore side of the runtime features would outlive the
WebKit API side of them...especially when more than just Chrome is using the
Chromium API.

I think you should commit this as is, but that we should think this through more
before we commit to it for the long term.
