Relying solely on prepackaged cold storage devices is going to get a lot of people absolutely rekt.
Fortunately, you can build a SeedSigner & use it alongside your current device(s).

Prepackaged cold storage is the only way for mass adoption for cold storage
The masses are not of my concern, but I also disagree.
Generic hardware is going to become the standard with software being flashed with ease.
Your favorite self custody software is more important than the hardware.
Everyone knows how to use a USB stick and an app.
What do you mean by prepackaged? And what is wrong with it?
Hey Michael, hope I didn't spook you.
My intention is to bring consciousness to the idea that Bitcoin self custody isn't dependent on corporations selling you difficult to verify hardware.
Bitcoin custody very much is reliant on Free & Open Source Software development of tools that can be improved indefinitely by whoever carries on the torch(es).
Bitcoin private keys are generated using easy to verify math, not hard to verify software.
To learn more, try to use bip39 word list & create your own random seed & subsequent wallet with the physical word list cut up into 2048 unique pieces.
Once you've created a wallet like this once, you'll understand Bitcoin custody better than most.
If you need help with this lmk.
I also recommend building your own SeedSigner to accompany this process over other devices.
That way you can understand the OP.
