Is there a higher reason for this change aside from "let's do it
because we can"? For instance, are subsequent changes going to take
advantage of features only present in more recent Git versions which
would be painful or impossible to support with the older Git?

The downside of this change is that, while git-subtree may live in
git.git, it's still just "contrib", so people might grab git-subtree
from a modern git.git but then end up using it with an older Git
installation. That's not to say that doing such a thing is guaranteed
to work anyhow, but we don't need to make it harder on people if there
isn't a good reason (hence my question about whether subsequent
changes will actually take advantage of newer Git features).
