As far as I know you indeed can't reverse T1D with keto, but making it (much) easier to manage still seems like a very big win.

It's actually pretty easy to get used to a keto diet. Initially you might crave a lot of food items that you were used to eating, but eventually you stop missing them. I don't feel like I'm missing out on anything when I'm having some aged cheese and roasted nuts as a snack (which replaced eating cookies or chips for me). It is a little bit more expensive though.

As for drinks, eliminating fruit juices and opting for the 'light' or 'zero' variant as a drop-in replacement if you want something sweet is pretty easy.
