Comparing with the MIT license apples-to-apples, I agree it's guaranteeing less. But most people just use the MIT license because it's simple, permissive, and very popular in certain communities. With both that and the ASL 2.0 being very popular and certainly known to Facebook's lawyers, they then developed this license. So the intentions mentioned in the parent speak volumes, IMO. I'd prefer not to use the MIT myself for these reasons, but I don't think most people are thinking about this particular aspect this deeply when they just slap a permissive license on their projects. I feel it's a little like this: https://www.xkcd.com/463/ https://www.xkcd.com/463/. Yes, the new license is providing explicit guarantees that do not exist in the MIT license. But... I'm not sure I like the thinking behind it when other licenses already address this in a fair way.
