This has been enabled on GitLab.com for over a week. There were hundreds
of thousands of `/internal/lfs` of API calls made from the new Gitaly

via a CDN on GitLab.com, and for self-managed hosts Workhorse also has a
local disk cache, so that mitigates any extra network traffic generated
by larger archives.
