If a git version of Hurd (or some other component) is needed, it would be 
reasonable to make vcs-mainline the default version of Hurd until there's 
a new release.  Longer-term (once Hurd is working on master) I'd hope 
there would be a clear (and documented) notion of minimum compile-time and 
run-time Hurd versions, as there is for glibc using the Linux kernel, with 
any features of newer versions being used only conditionally, so that the 
most recent releases are generally sufficient to build and use glibc for 
Hurd.
