Question

When create user with dot in username.
users.xml:
<ivan.petrov>
...
...
...
</ivan.petrov>

When checking the created account, via show users it shows the following: ivan\.petrov

Find
#6111
#27069
#58354

But they are all closed, without any solution :(

How can I resolve this problem? Or does no one need it?
