What a thoughtful and detailed reply; thank you; that is wonderful.
I hear you re coating, or seasoning, on pans that can be stripped off by repeated contact with the acidic delights of tomatoes (among other foods, but the most common culprit, in my experience).
Around twenty years ago, on a holiday with fellow foodies to north Italy, to the Cheese Festival in Bra, Piedmont, I treated myself to what was then a sort of holy grail pan - a hand made copper sauté pan.
The pan was (is) gorgeous, and superb, - I loved cooking with it - but came, as I subsequently discovered, with a fatal flaw, in that it was lined with tin, and our world no longer caters for such products, in that the cooking surface needs to be relined on a regular basis; yes, the pan has made subsequent return journeys to Italy, and has been relined, but I will never again buy a pan with that classic copper and tin combination, even though cooking with it was an amazing and much loved experience - the pan handled superbly, and was a real joy and pleasure, if something of a nuisance.
Instead, for copper, for the future, I have since selected Le Mauviel, where the copper is lined with steel; these are superb saucepans,
