New standard extension for Organization telephone opening hours

We have a need to communicate to patients the opening hours for reaching a clinic or hospital by telephone. This seems like a valid use case to be included as a standard extension.

Would it be an idea to include a standard extension on the Telecome data type for this? We would need to be able to say things like 8.00am-5.00pm, Mon-Fri, but I guess the rules can be more advanced than that (closed for lunch or other type of smaller availability periods per day, different opening hours different days). 

This type of information brings high value to patients, so hopefully it can be prioritized!
