Culinary purpose of frying pan foil sheet for cooking fish? (not wrapped in foil)
I came across some videos about how to cook mackerel (Chef Saito's Saikyo-zuke with Spanish Mackerel [Japanese Cooking] - Dining with the Chef) and several of them recommended the use of a "fish cooking sheet" that looks to me just like aluminum foil. They put this foil on top of a frying pan and then put the fish on top of the foil and then cover with a glass lid on low heat for 3-4 minutes before flipping.
Note, the fish is not sealed inside the foil with herbs and spices, and the recommendation is for low heat.
If any, what is the culinary purpose of using foil for frying pan (when cooking oily fish)?
It says one side is non-stick, but surely it is not just for help with clean up? Does it modify the heat in some special way not otherwise achievable without the use of foil?
The foil is from Japan, but the pictures on the packaging make it clear what it's used for.

It's a silicone-coated aluminum foil.
It's just something that makes your life easier when cleaning. You could just use a regular non-stick pan to get the same benefits.
There's no "culinary purpose" for it.

Do you have to wrap fish in foil?
Baking in foilLots of people prefer to bake their fish by wrapping it in foil. This method is very efficient, as it cuts down on oven and utensil cleaning time. By wrapping the fish in a protective covering, it has a similar effect to steaming, as moisture is sealed within the foil rather than escaping into the oven.What is the purpose of foil when cooking?
Foil conducts heat well in ovens or grills, withstanding excessive temperatures, so it acts as a good barrier to protect food areas from over baking, such as pie crusts and poultry skins, allowing the foods to cook slower and more thoroughly without burning.Can you cook fish in foil on a pan?
Season each fish and vegetable packet with garlic oregano oil. Top the fish with a second piece of foil. Fold both bottom and top foil pieces together tightly. Place the fish packets on a sheet pan and bake for 18-20 minutes.Why should you not cook with aluminum foil?
Aluminium is significantly more likely to leach into food, and at higher levels, in acidic and liquid food solutions like lemon and tomato juice than in those containing alcohol or salt. Leaching levels climb even more when spice is added to food that's cooked in aluminium foil.Asahi Kasei Frying Pan Foil - About

Answer 2
In my experience, when using non-enameled cast iron, the skillet retains a distinct fishy smell, and imparts that Umami note to any other food cooked in it. Even after scrubbing and re-seasoning, that skillet is no longer used for anything but fish, or something being served with fish. I have also noticed that one of my anodized aluminum pans, used once to sear tuna steaks, has a much less pronounced fishy aroma while preheating, but does not change the taste of the food. I have heard of this also happening when using carbon steel, but I have no first hand experience with that. My family does not dispute me on the cast iron, but thinks I am bonkers when it comes to the anodized pan. I won't deny that they may be somewhat correct; however, I have a much stronger sense of smell than they do. For example, I can tell from the other side of the house, behind a closed door when when something in the oven is done -simply by the smell. My olfactory hypersensitivity notwithstanding, if you are using non-enameled cast iron, I would definitely line it with something. Either way, as Max points out, it makes clean up a breeze. The silicone will make the fish release cleanly from the heat preserving that beautiful finish without flaking off into the pan. Silicone can't take temperatures much higher than 400f/200c, so do heed the low-heat warning.
Aside: Silicone-lined aluminum foil? That is genius! I wish I cold find that state-side.
