Why Limit the Days a User can Change their Username

What is the thinking of limiting the days a user can change their username? Is there a setting for unlimited?

Until somewhat recently when you changed your username you also broke quotes and some other continuity-dependent features.

This is no longer the case, but it can still be mildly annoying for others in the long-run. If someone changed their username every month for example, you’d have a hard time remembering what their username is if you wanted to mention them (people who do this definitely exist!).

There’s no setting for unlimited, but you could change the username change period setting to 9999 (~27 years).
