Initially, we designed an embedded plugin registry to have web-terminal plugin version per OpenShift version https://github.com/devfile/devworkspace-operator/tree/master/internal-registry/redhat-developer/web-terminal
And then OpenShift Console is able to patch terminal according to its version.

but then it was successfully forgotten and OpenShift 4.6, 4.7 creates terminals with 4.5.0 terminal.
That's needed to develop a plan if we still need to make OpenShift Console configure the specific version for Web Terminal plugin.
Since new WTO releases works only on new OpenShifts like WTO 1.1 -> OS 4.6, WTO 1.2 -> OS 4.7, we may just want to move to one web terminal plugin version like latest.

If so, we may need to provide the corresponding fix into OpenShift Console (DevWorkspace Operators still may have web-terminal 4.5.0 that will be the same as the latest for backward compatibility)
