Keeping 'origin/next' usable is a _must_, _if_ we were to go this route.

You seem to envision "auto-follow" to slurp remote tags in remotes/origin/$tag
namespace. What should "git fetch --tags $from_there" do?
For some reason, many people seem to be enthused about splitting the tag
namespace, but I am not sure if that is a good thing in general. Branches
are moving pointers for people to flip around in their local repositories,
and it makes sense to say "My master is a bit ahead of the public one",
but what would we gain by making it _easier_ to add and exchange many tags
with the same name (e.g. refs/remotes/*/tags/v1.7.4 vs refs/tags/v1.7.4),
other than the extra confusion?
While you are talking about drastic reorganization (and rewriting the ref
code to support it), another possible Sub-proposal we may want to consider
is to allow "next" and "next/foo" at the same time.
