Yes, and a 3-wire dipole nearly doubles the SWR bandwidth relative to a regular dipole.  

As you say, the antenna is not useable on even harmonics but for some, having to put up a separate 40-meter dipole is a small price to pay for being able to cover a large chunk of 80/75 meters without having to retune an antenna coupler.
