Add read only attributes/user details

Hello,

Is there any possibility to add a read only custom user attribute/data?

For example, a bool variable for accepted T&Cs? If the T&Cs are accepted, naturally the users should not be able to modify the attribute value.

Is this possible, without changing the code?

Not possible without changing the code.

Thought so. It might be a useful feature though. Will add it on GitHub.
