The existing guideline covers that and considers it compliant, so it doesn't matter.  However,
I've found that statement doesn't apply anyway in the situation when you use either commit hash or Git tag.  
I thought I had deleted that checksum error reference, but I forgot.  Thanks for pointing it out 
to remind me to delete it.  The checksum matches, I've tested it out myself using fedora-review.
