If a Bitcoin core developer couldn’t be bothered to keep a hardware wallet, why would a regular Joe be bothered to do so.

Also, how is having a hardware wallet supposed to be secure? Hardware wallets may get stolen, lost, damaged, etc.

Edit: Also, the link you have shared doesn’t even allow you to choose the “New” user type option if you pick a hardware wallet, allowing you to choose only the Experienced user type option.

IOW, a hardware wallet is something that’s only considered usable by someone who is experienced.
