I wouldn't mount it on the front, but I'd definitely wear that one out positioned on the rear.

Same-- only for me it's super glue on the outside, and Gorilla Tape on the inside. Super-gluing cuts on tires is a normal activity for me. So long as the hole isn't getting any bigger, ride it. My back tire has threads showing in a couple of spots. Still riding it. They're tires, not Faberge Eggs.
My last tire that got trashed early had a cut so big I could fit my pinky through it. What the OP has got is barely a flesh wound.
