WildFly - How to get the main configured JSF version with "jboss-cli"?

Question

I would like to get the main configured JSF version but

[standalone@localhost:9990 /] /subsystem=jsf:list-active-jsf-impls

leads only to

{
    "outcome" => "success",
    "result" => ["main"]
}

Moreover no solution with

[standalone@localhost:9990 /] /subsystem=jsf:read-attribute(name=default-jsf-impl-slot)

{
    "outcome" => "success",
    "result" => "main"
}

When I run wildfly the output is

09:35:41,830 INFO [javax.enterprise.resource.webcontainer.jsf.config] (ServerService Thread Pool -- 78) Mojarra 2.3.14.SP01...

But how to get this version with jboss-cli?

Have I overlooked something in https://docs.wildfly.org/21/Admin_Guide.html#JSF?

WildFly 21.0.0.Final
