Good to hear, hopefully the task decorator will make it in soon because I think it's a much superior API.

The little hack on Fabric I use currently takes the opposite approach -- I use an @internal decorator that hides certain functions from the task list but keeps the default Fabric behavior around for anything else. It's just a few lines of codes that mess with a private list Fabric uses to track internal functions:

    from fabric.main import _internals

    def internal(fn):
        _internals.append(fn)
        return fn
    _internals.append(internal)
