You don't really think that this is an issue which means it will be years before it is addressed.
You're making the classic mistake of reporting an issue assuming that your *proposed *fix* is the *issue*. Mark replies that the immediate issue is not that a database record of the user is retained, it's that there's no way for an authenticated user or even an authenticated list admin to change that user's display name in the database. It's a database, there *is* a way to change it in Mailman, it's "just" that it requires site admin intervention. (Assume "just" is marked with the nonexistent sarcasm emoji.)
It's arguable that there should *also* be a way for a person to delete their user entirely (in fact, some interpretation of GDPR say that "it's the law" :-). But that's not the immediate issue faced by *this* user and list admin, and I doubt deleting the user object is a big issue for users (but it might be for admins because of GDPR etc).
Whether it gets addressed this week or sometime in the next few months or in the summer is something you're more than welcome to advocate. Like Mark, I recommend filing an issue.
