It is well supported on AWS as well, and a variety of bare-metal solutions (e.g. Red Hat Atomic, CoreOS)
However, concretely, it is a challenge to maintain good support for N different platforms without an owner who is willing to stand up and ensure that it works, and continues to work for that platform.
We have gotten a number of drive-by contributions of "how to" guides that (sadly) bit-rot over time. As always, we're working on improving the situation, but it is complicated and requires a great deal of time and access to infrastructure (e.g. Rackspace) that the core team simply doesn't have.
