Why we use Hidden CDT ? where to use it?

Question

Hi Folks , 
 When we create a CDT we get an option to hide it from pickers and auto complete , what's the use of it , in what scenarios can we use it ?

Another scenario if when you create the CDT from a schema imported in a WSDL. IN that case the CDT will be created as hidden

Typically, I would use the hide from pickers if it was a deprecated CDT that I wouldn't want other developers to include in their apps.
