Just read about this dude on dedbird who had a coldcard, but entered his seed phrase into a fake sparrow iOS app and lost his whole stack. Maybe nostr:npub1tkey6tcfk0jf2ageje7xvqnnph4443h4pc4aqesuqjeywyke073qfmwral is on to something with the whole seedless thing. Coldcards should ship with stickers that say DO NOT EVER ENTER YOUR SEED PHRASE INTO AN APP.
