I know only .01% as much as Jim but I agree to cut it out for sure.
But I would keep an eye on it, and wait until a couple days after some new brood is out, because that white wax will crumple especially in this summer heat. Also the swarm bees will be old then, and some brood will be lost in the cutout, and it will keep population higher if the first round hatches, so there are new nurses. Losing only eggs ... less impact than losing capped brood. I'm sure there will soon be brood in all stages soon if you are feeding tho...
But one generation through the comb, and the comb will have a cocoon to make it stronger for the cutout.
And I would reduce that entrance more against SHB, moths, robbers.
