Sounds reasonable to count Imports, so we'll alter this.

Thank you for the report,  However, the pre-test period for 2.12.0 is 
already 80% over and we are in code freeze -- reports early on in the 
period are much more useful and at this stage anything but very simple 
localized changes need to be deferred to 2.12.1.
