I get your point but is a large set of dictionary words or 5-digit numbers (see the current backup passphrase) so much better? At the end of the day, recording entropy will always be cumbersome and there is no way around it.

At least on Android apps can disable screenshots, though, which might be a simple way to deter people from doing that?

I think a large set of dictionary words are likely more user friendly. I think most people will have a lot more confidence on their ability to transcribe words to/from paper more accurately than a bunch of numbers - better built in error correction, etc.

Sanely formed numbers (like 4 digit groups with a checksum) seems like less writing to me, b/c I hate my hand writing.

Yes, much easier to type

And much easier to copy elsewhere or memorise (not that I would recommend the latter).
