Many barrels are ported by EDM. This is a similar port, although closer to the breech.
The concerns are similar to suggesting you should not put your finger over the muzzle of a short pistol while shooting or over the cylinder gap.
Do you hold your 12" barreled Grendel with your left hand on the muzzle brake?
I don't see the problem.
I did show a photo of what happened when I camo taped the barrel.
It did burn a hole through.
It did not burn a hole through a carbon fiber handguard or a Schedule 40 handguard.
These had a clearance of about an inch.
