This looks great @vdice
The preview works perfectly; is there anything you would recommend I go ahead and test on purpose?
Otherwise LGTM.

Thanks @tpmccallum! My only question mark is the spin-version-proxy component. Notice how it has changed from allowed_http_hosts = ["self"] to allowed_outbound_hosts = ["http://self"] which I understand and expect to be functionally equivalent -- but can we double-check that this component/logic is working as intended?

It correctly redirects to the v2 version:

In addition, if I toggle between version 1 and 2 it works as intended.

LGTM and good to merge.
