Most interesting, and I require al dente pasta. The salt is an absolute necessity, though as long as it isn’t iodized, any will do in the pasta water. Olive oil has no essential use in pasta water (presuming it is prepared correctly) according to Marcela Hazan, many years ago.
When I have to make gluten free pasta for guests, I cheat and use olive oil in the water and then “lift and lower” the pasta as it cooks in order to get a little less noddle sticking in the cooked pasta.
For “normal” pasta, I agree about oil not being a necessity.
