In ARS WI, for commands, is there better way to handle 'NOT' clauses for visibility?

9 years ago Sargay (dev) indicated that the condition designer in the web form for commands didn't allow for 'not' conditions in visibility settings -  only true or 'is exactly'

in the intervening years, has this been revisited? Or has anyone come up with a better solution to display or hide a command based on the content of another attribute, where that other attribute could be a false or empty value
