they do not have any electrical property that is polarity sensitive
It depends on the type of electrical symbols. There are safety and warning symbols as well as symbols for identifying parts and their polarity. The symbols are needed for maintenance for proper safety, part identification, and to know how to hook up things. It's much more convenient to have a symbol that everyone recognizes for, say, a resistor, than to glue a resistor onto the wiring diagram.
