Yeah, I guess it's true that there are sometimes deprecated resource
interfaces that get removed on upgrade to a new OpenStack version, and that
is independent of the HOT version.

As we've proven, maintaining these templates has been a challenge given the
available resources, so I guess I'm still in favor of not duplicating a bunch
of templates, e.g perhaps we could focus on a target of CI testing
templates on the current stable release as a first step?

Agreed, getting the approach to testing agreed seems like the first step -
FYI we do already have automated scenario tests in the main heat tree that
consume templates similar to many of the examples:

https://github.com/openstack/heat/tree/master/heat_integrationtests/scenario

So, in theory, getting a similar test running on heat_templates should be
fairly simple, but getting all the existing templates working is likely to
be a bigger challenge.
