No way would I as a controller consider interfering with the work of a marshaller, TCO, or anyone on the apron. Not my manor, guv. I only "Assist in preventing collisions between aircraft on the apron." If my airfield is worth its salt, any staff operating on the apron are subject to their own apron rules and regs, with oversight from their company and, almost certainly, from the airfield safety team, who will conduct ramp audits on their performance and investigate reported incidents.
Use of remote tower technology can clearly deliver economic benefits, and delivers benefits in resilience. Like it or not, it is the way forward for economically challenged airport businesses.
