Ok, so this needs more context. Currently I have a built in countertop glass top stove. I got it from the habitat for humanity restore for 40 dollars years ago to replace the even shittier one that came with the house. It's served me well, but it has been a bit of an abusive relationship. More me abusing it than the other way around. I just never cared though. And it's not in the worst shape, but it's not exactly well taken care of. I cook at least every other day with cast iron on it, but to be fair, I'll cook popcorn in my stainless steel pot and shake it back and forth while it's still making contact with the glass. So all the wear and tear is not necessarily from the cast iron. But anyway here is the main burner and what it currently looks like.

Now fast forward to today, and I am buying a new stove. I've never had a new stove before, and while I get that it may not be the top of the line best of the best, it is the most expensive appliance I have ever bought, and I want to take care of it.
The link to it is here https://www.homedepot.com/p/GE-Profile-30-in-5-Burner-Element-Smart-Free-Standing-Double-Oven-Electric-Range-in-Fingerprint-Resistant-Stainless-PB965YPFS/315518806.
Now the user manual says very specifically not to use cast iron on it. In the questions and answers section, GE themselves respond to people saying don't use cast iron, as do some other people who have purchased the stove. Yet my instinct tells me it will be fine if I'm not dong stupid stuff like sliding it around on the glass when cooking. But also I will be mad at myself if I am wrong and I my new stove gets all scratched up within the first few months because I didn't listen.
So I ask you all in the cast iron subreddit for your obviously unbiased opinion. What is the right thing to do here? Will cast iron hurt my glasstop? Would you use cast iron on this? Would you care about scratches? Any advice and/or anecdotes are appreciated and helpful!
