> You can’t wear 99 in the NHL now, or 6 in the NBA. Maybe you shouldn’t be able to log in as dmr for the same reasons

I can't tell if this is a serious argument or just relying heavily on the use of "maybe" to get away with expressing something that they know most people will disagree with, but I feel like it's a huge stretch to imply that what makes sense for numbers on maybe a couple hundred professional athletes' shirts when they're playing publicly on televised events would apply at all to usernames for millions of normal on their own private devices. To just call out one of the many obvious concerns: this would presumably break any existing logins (and scripts referencing the home directory). The MLB even took this into consideration when they retired 42 for the entire league in honor of Jackie Robinson; any players currently using the number were allowed to continue using it until they retired, and that's was just out of courtesy rather than any actual necessity.
