Hi all, I think we should strongly encourage web devs to move away from sync XHR (in Window context, not in Workers). It is bad for UI responsiveness.
Unfortunately sync XHR has been used quite often with the old text/xml types. But maybe we could disable sync XHR for the new types, and also make .response to throw if it is used with sync XHR.
