The work group is deprecating the current code at Swift on Server · GitHub. A good portion of the code there has been replaced by SwiftNIO and remaining parts should be reconsidered. For example, things like safe HTTP header access should be added against SwiftNIO's base HTTP types instead.
We are hoping to start a discussion soon (in this forum, EDIT: Server work group, new focus areas) about which packages the community would like to focus on first and a new process for creating those packages. Once that is all decided, I think these deprecated repos will prove valuable as reference material for future discussions.
The READMEs on those repos will be updated soon to reflect their status.
