As such, the core team feels that it isn’t overly burdensome to ask that imported Objective-C APIs annotate their semantically noescape block parameters with the clang __attribute__((noescape)) attribute.

It was my impression that Philippe was making progress on this, but I hadn't heard any more for a while. (My concern would be APIs getting missed due to lack of community input.)

At this point it is hard to say.  All I know is that the only process for this is to discuss it on the list (in which case many Apple folk will probably notice and make take it up on their own volition) or by filing a bug with bugreporter.apple.com <http://bugreporter.apple.com/> requesting it.  Neither of these approaches give you the transparency you seek into when or if it will happen.

I understand that this isn’t what you want to hear, but it’s just the reality that Apple’s general framework design and evolution is not governed by the swift-evolution process.
