There are several wallets that make you reenter you full seed before they will let you continue, forcing you to write it down.

That's a cute idea. Let them hit "Next" and then surprise attack with it, giving them a "Wait! I didn't write down my seed, go back" option
There certainly is something to be said about "shock value" x)
Ngl, I usually just uninstall at that point. If a wallet has nothing in it, it’s not valuable yet.
It’s only valuable in the person’s mind when it holds money. Sometimes I just want to check out an app UI and see if I like it first
