Anyone care to speculate why this isn't a thing? (announced at least)

The infantry command unit for Waiqar can be used with both units that ship with the core, but the infantry command can only be used with the spearmen.

Of course, we're also missing expansions for the Daqan Spearmen and the Waiqar Infantry, so I guess it could be announced with those...

Maybe are they waiting to announce mounted heroes to have the command unit make its coming out ?

I was wondering too if maybe their somehow "unique" - i.e. "Oathsworn Cavalry" as opposed to "Daqan Cavalry", and the mounted hero (Sir Hawthorne?) may be their command option...
