Thank you Christian. There is a potential use case - training/classes.
Having an SNO for every student in class instead of a full 5 nodes cluster
(or even 3) is much more feasible.
And in general, I would think there are clients out there who don't have
enough memory and IFLs at the moment on their mainframes to spin up an OCP
cluster with 5 nodes so giving them SNO would give them at least a chance
to try it out. 8vCPUs/32G/120G is much more appealing for a small POC :)
Besides that, installing SNO, probably would be much easier and faster than
installing a full cluster so less terrifying for new users who just want to
see if it works with their apps.
x86-ers have SNO. It would be nice to have it too :)
