I'll make the contrast.

The second is a more elaborate version of the first.  More elaborate
than necessary in my opinion.

But we can start with the first right now by just adopting practices
in common usage.  It is common to have a "stable" trunk and
develope on a branch, test the branch and merge into the
release version.  BTW its already being done now by some
developers.  I'm doing it, Beman is doing it Joaquin is
doing it (witness that he has been able to provide an increment
to to multi-index).  I'm convinced that little by little more
developers will migrate to this model.

If in the future, its necessary to make this even more elaborate
that can be considered later.
