My county sheriff's office has started giving out these envelopes for people who have trouble communicating. Clearly more geared toward people on the autism spectrum but thoughts on carrying one as a PWS?

My county sheriff's office has started giving out these envelopes for people who have trouble communicating. Clearly more geared toward people on the autism spectrum but thoughts on carrying one as a PWS? I think it's a pretty cool idea, though personally I think I probably won't carry one. Based on a super quick Google it seems the Autism community doesn't like them very much, how does everyone here feel?
