Of course not, everything can and should improve, whatever it may be!
No, I am a familiar with what they are doing in regards to collaborative custody, and worked with some of the guys at unchained, so I’ll have to take a look as I haven’t checked in on them recently.
It's the silicon inside that brings the security. You have 256 bits of information that should never ever be read by an attacker. The device that secures the key can be light as a feather. The access controls around it can be as hardcore as a military base, and that part is all up to you. Make it as beefy as you want. Or put it in a drawer who cares.
Should the signing device be bigger, harder to break, or what? I think imprinted in steel is as good as solution as you can have for physically securing something. At the end of the day, physically storing wealth has always been a challenge. It’s going to take some invention to solve that has eluded mankind forever. This is a meat space problem, not a digital one. The alternative is to trust third parties with it, and you are just trusting them to secure it properly. I know which option I’m choosing.

yeah I don’t get his deeper point or what he thinks would be better.
Making the device more durable if you have your seed phrase(s) in steel is completely counterintuitive. If anything, we should have throw away, one use, cheap signers for moving material amounts of wealth. As far as using a signing device in its current setup, simply as a facilitator to sign something, I see no problem with them if you are properly securing your seed words. Would you really pay for what you’re asking for?
No, Glacier protocol is way better. Also, multisig with geographic separation would mean you'd need at least two pieces of plastic, using off the shelf stuff like coldcard. Well...unless you just travel with it to your stamped seed words. That all said, don't judge digital money storage by physical devices used to interact with it. Any old airgapped computer will do. Steel or titanium backups are the REAL storage security against loss. You can use a signer in stateless mode, or even use TAILS OS for the task. If you're worried about the backups being compromised, generate a one time pad, hammer THAT into steel too, and store your encrypted backup geographically separately from the key. There's no shortage of paranoia to go around.
