Ironically, I think it's actually slightly easier for an eavesdropper to detect that your keystrokes are part of a password if the password is not being echoed.
They could potentially use this information to know the length of a password, which would make brute-forcing easier. A very hypothetical attack, but fun to think about! Less effective than a $5 wrench, no doubt.
