I intend to merge the cordova-ios 4.0.x branch to master. Most of the remaining issues in https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=76 are related to the CLI or the wkwebview-engine plugin, not platform issues.
I'll resolve any outstanding PRs first. I still intend to implement Workspaces since I think that's important for 4.0.x and will do that in another branch. Thoughts?
