Right now, we retain support for Go 1.7. The main pain point this causes is that we have a bunch of junk sorting types, just itching to be replaced by sort.Slice().

I'd like to replace these once we think it's safe to do so. One reasonable measure for "safe" could be the state of the RHEL repositories (or at least EPEL). CentOS seems to have 1.6, and RHEL none at all; EPEL has 1.7, assuming I'm doing that search right.
