The “generics manifesto” is a set of ideas that are *heavily* biased by my own 
goals for the generics system. They’re not plan-of-record, and some might even 
be terrible ideas for Swift. Each thing there still needs to go through the 
usual swift-evolution process to get proper design treatment before becoming a 
part of the language, and I expect that process to flush out better 
ideas/problems with those ideas/unexpected interactions/etc.

Yes.
