In upstream it is created a new channel to install Eclipse Che Operator in AllNamespace mode and add the DevWorkspace OLM dependency.
(As of Sept 7, this channel is called "tech-preview-stable-all-namespaces".)

In CodeReady Workspace would be nice to have a similar channel to start to see how the installation in AllNamespaces mode is working for CodeReady workspaces with DWO olm dependency

Suggested new channel names:

• stable-ocp46-eus [2.11, 2.12, ... - see CRW-2128]
• fast-ocp46-eus [currently empty, nothing to put here as no new tech preview stuff being rolled out for 4.6]
  and
• stable-ocp48 [2.11, 2.12, ... - see CRW-2128]
• fast-ocp48 [2.11 w/ allnamespaces + DWO enabled, 2.12, ...]
• candidate-ocp48 [2.x CI builds only, likely out of scope for 2.11 - see CRW-1759]
  and
• latest - if we keep this, I would point it at ocp46-eus-stable; but I would argue 2.11 is a good time to REMOVE the "latest" channel
   
  In future we would add ocp49 and ocp410-eus suffixed channels, but until content deprecation (OCP 4.10) or cross-channel updates (OCP 4.?) are feasible, users will have to manage their own manual subscription paths.
