Comment (by wppunk):

 @hellofromTonya It shouldn't work in this way if this code worked for the
 int, float, bool types. That means the documentation was incorrect.

 If you want to change this behavior and support only string values:
 - Firstly, show a deprecation message and support undocumented variables.
 - A few releases later, it is possible to remove support undocumented
 types.

 Why do I insist on this? Because this bug is floating, it is pretty
 challenging to find this floating bug. For example, in my code, all
 checkboxes are deleted after saving. Let's come up with a blueprint for a
 smooth deprecation process.
