I think you can manage T2 diabetes with diet and exercise alone, such that you have non diabetic numbers. Some people may prefer to think of themselves as 'cured' - even if that is for just as long as they keep on the diet. Why not think of yourself as cured, it may be good for your soul, for your self esteem, for your own image of who you are.
For many people, the LCHF diet involved brings many benefits in addition to achieving normal blood sugars. For me, such is my feeling of well being that I know I will never revert to a diet high in carbs. My body simply functions better on 30g a day, or less.
But this diet has not really been around long enough (well actually, that's not true, until the middle of the 20th century, perhaps up till the late 70s, it was the diet advised to diabetics), but in this day and age, few people have been doing it for 10, 20, 30 years, so we still don't really know whether, long term, it will keep diabetes at bay for ever. I like to think so.
For me, if you like to think of yourself as cured, provided you continue to adhere to a diet that you enjoy, that's fine, it's a positive mind-set.
