On a 4.4 cluster there is only a single image registry pod running by default. All of our components must run in an HA configuration by default (2 pods with normal spreading).
This must be backported to 4.3.
Note I'm fine if it's only 2 when the default backend is object storage (clouds)
Verified on 4.5.0-0.nightly-2020-03-11-214319: there are two image registry pods running.
