The bug
Previously, whenever you tried to change your username on account.mojang.com, a dialog box would appear as soon as you clicked "Change name", confirming that you really want to change your name.
This dialog box doesn't appear anymore.

No. There used to be a confirmation box – unintentionally hitting the return key on your keyboard while having typed in your pw and a potentially unwanted username instantly results in your name being changed for 30 days with no possibility of reverting back to the old one within that time span.
But changing your username requires you to enter your password. Is that not enough?
