I have started to play with OpenShift XP image docker-registry.upshift.redhat.com/kwills/eap-xp1-openjdk8-openshift-rhel7:EAP7-1484 and I have noticed it is nearly 2GB big. Used to be 0.92 GB for 7.3.0.GA or CD19.
Also strange is there is much more layers compared to several layers in previous releases

From dive output it seems every bash command result in own layer. Dive is reporting 624MB of waste space.

I am setting priority just to major because it is not official image yet. But if this will be the case of official image as well, I will raise priority. In OCP 4 there is no image/layer cache so image must be "downloaded" for each build from registry into pod.
