I don't have a strong opinion on this but I have basically the same concerns with completely opposite conclusions. To me, the distributed thinLTO makes you think there is a distributed full LTO, while just call it distributed LTO will eliminate that confusion. Distributed LTO is by nature based on thin LTO infrastructure but that doesn't need to be exposed. Isn't the LTO option to be `Full/Thin/Distributed` cleaner?
