I don’t see it being a threat.
I personally signed a transaction today via Nunchuk / CC MK4
I feel like you are splitting hairs there 🙃

It’s only a max ~800 bytes and that’s pushing it
Future will fix the bandwidth
Yeah. Perhaps I'm just overthinking due to how nunchuck not putting adding coldcard key under the air gapped definition..
Thanks guys
