The Swift memory model is current incoherent; this is an attempt to fix that. (defining accesses properly, properly preventing conflicting accesses in single threaded ways)

Boring single-threaded swift code can currently be incredibly slow for no clear reason; this is an attempt to fix that.(addressors++)

The details this manifesto covers need to be settled for ABI-stability, which is still one of the primary goals for Swift. (because it enables making it a part of Apple's OSes)
