Considering that DKA accounts for 160k hospital admissions a year, your lived experience translates poorly to such a flippant dismissal.

I agree, but there are a lot of factors going on to contribute to that number.
For example, about 20% of that number is because someone is finding out for the first time they have T1D [1].
Insulin costs and monitoring costs are also going to be a pretty big contributing factor. CGMs and finger sticks aren't cheap.
IDK how often it happens that ketoacidosis happens when glucose appears to be fine, I assume it's pretty rare.

A CGM that has ketone levels is quite literally pointless. If you have a CGM in the first place you would know if your sugars were high enough for long enough to get DKA.
DKA is what killed the legendary Dan Kaminsky.
In diabetics, DKA is preceded by hyperglycemia. Meaning, a CGM would tell you earlier that you are at risk for DKA than a CKM, a CKM would only tell you after you got it. Hence grahar64 is absolutely correct that as far as we know now, this provides no benefit to people at risk of DKA that a CGM does not already provide. I'm sure there will be some benefits but its really not clear at this point.
