+#### Heterogeneous clusters
+
+To support [Heterogeneous clusters](https://github.com/openshift/enhancements/pull/1014), we clearly now need to generate
+an image per supported node architecture.
+
+Today as noted, OCP native builds do not support this.  It seems likely that the MCO will need to
+generate a build per supported archicture itself, and handle rolling them out.  This is its
+own large topic, such as whether we try to use a fully-fledged solution for that or hand-craft
+something that just handles monitoring OCP native builds and manifest list pushes.
