Stars on the wrong side

This is weird. Have we ever done this before?

Do we still build back to 10.11? What's up with all of this. Should/can it be a specific HAVE() or USE() instead?

Good point. The ways in which we handle errors is pretty inconsistent already (some places in WKWebView use [[NSError alloc] init], and other places in attachments code use WKErrorDomain, but with error codes that are not exposed anywhere). I filed <https://bugs.webkit.org/show_bug.cgi?id=188860> to clean this up.

You're right! It looks like there are no more El Capitan bots on build.webkit.org, so I should be able to just remove all of these version checks.
