That makes sense. I was thinking more of the ER using it than the first responder, but it is still probably not a great idea.

The road id offers either just a tag or a service that you can update data on. The thing is I am not thrilled about getting more and more things that have an ongoing charge. I have gotten to where I just say no to them. I don't have a InReach Mini, gave up on mapmyride, strava, and a lot of other stuff for that reason. I get it they want ongoing profits, but I am not interested in ongoing costs. I may splurge on a one time cost, but hate these annoying ongoing costs. They seem small, but little by little they add up. They tend to be forgotton and go on forever even if you no longer need them.

I wonder if adding a url to my dog tag is maybe an answer. It could link to a Google doc or a personal web page with the appropriate data. A possible alternative might be a laminated card with a QR code on a lanrard around the neck. Some care about what was shared that way would be required, but I'd be cautious about the same with sites like road id as well.
