Usernames in admin URLs cause routing problems

Contribute Bug

I’m really with @sam in this case:

  • So far, the blocked usernames only contain confusing usernames (that look official or unintentional), not ones that break the system.
  • This list is admin-editable, nothing is preventing the admin from removing entries. This would have non-obvious side effects.
  • If I understand correctly, changing the default won’t affect systems which already customized the list, for example by adding an entry.
  • I have a strong feeling that there are more cases like this. I think that account-created is safe only by coincidence, not by careful consideration (“there could be a username here, so let’s add an invalid character…”).

Also, I don’t see the drawback: /admin/users/1/sam is perfectly fine for the admin’s eyes (heck, t/usernames-in-admin-urls-cause-routing-problems/31825 is fine for everyone’s eyes!), still has the slug (which is nice), and even works as a permalink across username changes!
It would also fix some issues for free: For example, after renaming a user, the back-functionality breaks, since the old URLS 404.
