We were having some issues with sudo's shell encapsulation. These are unresolved issues that even the maintainer of Fabric knows exist but isn't the mood to track down, and is thus removing the functionality entirely in Fabric 2.0.

I was able to come up with a work-around more recently that is cleaner, but I hadn't cleaned up this section of code yet.

Generally speaking I don't touch any of the devops code, even for cleanup, unless I'm currently in the process of using it to deploy something I'll actually use, that way I don't change anything that'll break two weeks later and I won't remember what I changed.
