So is it safe to assume if window.XMLHttpRequest exists there won't be some kind of error when calling xhr() should there be a try-catch for this flag ?

That's probably a safe assumption - we don't wrap the xhr() call in a try/catch now, inside ajax(), and we don't have problems. Most of the exceptions occur either with setting headers or sending.
