That’s also questionable. Rotax went through a ~5 year phase where they recommended dielectric grease on spark plug threads and applied it to newly built engines. After that, they did an abrupt 180 and issued Technical Service Bulletins saying not to reapply it when replacing spark plugs. And AFAIK, they stopped using it in new engines.
I use Rotax as an example because I trust their tech. They make some of the best engines in everything from aircraft to motorcycles.
Also I note your original plugs did not have dielectric applied.
correct, they did not, since I was swapping the coils this time around it was recommended to me so I added a pea sized dab to each coil before I installed them.
Anti-seize no, dielectric grease yes.

Yeah, honestly I never saw issues one way or another, but I assumed they had good reasoning.
