You're making it that much easier for someone to brute force logging in or to exploit a known vulnerability. If you have a separate root password (which you should) an attacker needs to get through two passwords to do anything privileged.
This has been considered an accepted best practice for 20+ years and there's little reason not to do it anyways. You shouldn't be running things as root directly regardless.
When you have secure passwords kr key auth. Brute force is not a problem. What vulnerability are you talking about? Complete auth bypass? Then the username would be no problem either since you can just brute force usernames.
Heartbleed was a thing that happened.
