Well I assume that people building one of the releases want something
relatively stable and supported, so xen-tested-master is obviously
unsuitable (and might not actually be capable of building against Xen
versions older than a certain point due to the fact that libxl cannot be
both forward- and backward-compatible). And I also assume that people
building with XEN_RELEASE="master" want the bleeding edge of everything
so that they can test new features (or indeed, so that they can write
new features). So I think we actually do want both -- a maintenance
branch for releases, and xen-tested-master for developers and
bleeding-edge users.
