Ubuntu 20.04 Security Vulnerability

Ubuntu Linux 20.04 LTS has made login passwords displayable with a button in the way WiFi passwords usually are. While this may have some utility, it presupposes the cleartext form is stored somewhere, which could be a vulnerability or at the very least could be said to increase the attack surface of the system. I think for WiFi, the cost/risk benefit is okay; for user and root passwords, however, I think the risk by far outweighs the benefits.
