Default country and unlimited values breaks validation

Problem/Motivation

Default country and unlimited values on address widget breaks validation/submit as other address fields gets validated even when they don't have to.

I've a content type with an address field "field_address" which is shown conditionally using form state if another checkbox is selected ("field_show_address"). If "field_show_address" is not selected "field_address"'s state is "visible = FALSE" and "disabled = TRUE" which works fine: if I submit the form "field_address" is not saved on db even if it's populated.

If I turn on "default_country" on address widget it breaks: address's fields get validated even if address's state is "disabled = TRUE" and I can't submit (see image attached).
