Most hardware wallets make entering a strong passphrase cumbersome. Even if the thing has a decent keyboard (which none do, not even LOL'DCARD), do you really want to type a long passphrase every time you use it? Most hardware wallets encourage the use of weak passphrases. That weakens security through bad design.

Have you ever held a Foundation Passport in your hands and tried to type in passphrases? I've already written that it's the same as typing a message on an old model mobile phone and it takes me less than 1 minute to type 20+ characters, noting that I have no need to rush.
Less than a minute to type a somewhat strong passphrase vs instantly scanning a QR code with a very strong passphrase.
If you really sit down to time it, since the Passport doesn't have an alphabetical keyboard, I bet it actually does take longer than you think. That method is fine for a weak passphrase, but not a strong one.
I don't know why you need a 50-character passphrase, but if you think you're safer that way...
Ask the people who used ColdCard and got robbed if they wish they'd used a strong passphrase.
Hackers began cracking weak passphrases for ColdCard seeds, most likely for seeds with wallets they suspected were just decoys.
Here's a video
that explains passphrases and how to pick a strong one.
Passphrase QR makes it really easy to instantly load a very strong passphrase.
Pro-Tip! Want to use a decoy wallet? Don't use it as the seed-only wallet. That gives anyone who finds it a clue that the seed has been used. Instead, hide the decoy behind somewhat weak passphrase. That way, if the decoy wallet gets found, you know for a fact that somebody is trying to crack your passphrase. And by using a strong passphrase, you know you have time to move the wallet.
