Comment 1 for bug 2054233

The branch working/user/gmcharlt/lp2054233_eg-form-org-select-wip has my WIP. Thus far, looking good for making it possible to mark an OU field as required in an FM editor form.

Noting that it's possible that I may end up working my way towards figuring out that eg-org-select can be modified to support CVA and behave fully properly in forms - though if so, at minimum persistKey's behavior would have to change.
