hi, there!

Seems like a good idea. I thought just about the same today

Any objections if I commit this?

Here is quick'n'dirty fix to adduser (this should be done more politely,
sure ;-) to put '*' when password is empty to not open your system with
passwordless user between adding new user and changing its password.
