I don't mind the existence of "\box_use_clear:N" (or whatever) but I can see your argument against it.

If not, I'd be happy to drop the use_clear function for the reason of consistency, as you note. Over all, I think 'void' is possible still the best choice. It suggests more than just 'empty', which 'clear' does not. So \box_void:N, \box_if_void:N(TF), etc., seem best. -- Joseph Wright
