Execute Console Command is a development tool, not a runtime API
Execute Console Command is declared in the Development category, but unlike Print String it carries no DevelopmentOnly flag, so nothing in a graph marks it as a development tool. In runtime code it writes every console variable at ECVF_SetByConsole, above scalability, user settings, Project Settings, device profiles and hotfixes. It reports no failure to the graph that called it, and the same string resolves differently in the editor and in Shipping.
