At least when Dave Taht was pushing his "make the class E space usable", he had patches and testing for multiple systems. Turns out that not many systems check for 'first octet >= 240', but actually test for the class D space and using class E Just Works an amazing percent of the time.... (Yes, I was surprised myself, but deploying it is still very much in the "effort better spent deploying IPv6" territory...)
