I fixed a lot of tires over the years with holes and never had a problem, these aren't car tires expecting to do 70 mph on 110 degree pavement for 100 miles I use to ride the mountains of California on hot days sometimes doing 60 mph plus and never had an issue with a booted tire. BUT, I haven't seen your tire, so I can't make that decision for you with any degree of intelligence, just saying the tires I booted over the years I could see the damage and thus determined that I could boot it or had to chuck it. I did once boot a tire that left the tire with bump as it rotated, it got me home where I chucked the tire.
Due to my former years of riding on tubulars where I got into the habit of carry two spare tubulars I still to this day carry a spare clincher ultralight tire that is folded and bound tight with strong rubber bands. Over the last 30 years or so of carrying a spare clincher I only had to personally use it twice, and a third time giving my spare to a stranded rider. I contemplated in recent years whether or not to continue to carry spare for my daily riding because road tires are far better today than they were 30 years ago, but I can't seem to get myself to the point of not carrying it. I will always carry a spare tire when touring though.
