Are there any details on LFC so other ports can determine whether or not they can or should enable it?

(In reply to Don Olmstead from comment #13) > Are there any details on LFC so other ports can determine whether or not > they can or should enable it? This is internal yet (not even an experimental feature). Nowhere near ready to turn it on (and even when it is on, it just runs as a secondary layout and the tree it generates gets verified against the original render tree.) I am planning to write up a blog entry on this, but the short answer is no. No ports should enable it at this point.

Thanks for the information! I saw this when I was looking at syncing the CMake and XCode feature set but was unsure what was happening. Looking forward to the blog entry
