Synchronous XMLHttpRequest in the window (not worker) context is an abomination, but we have to support it for compat reasons.  For new response types, though, we don't have this legacy constraint. Mozilla has floated the idea of not supporting any new response types in sync XHR as a way to encourage authors to stick to asynchronous mode and I think it's a great idea.
