As far as I understand target_pointer_width is at least 16 so <usize as std::convert::From<u8>> and std::convert::Into<usize> for u16 could exist.

This has been proposed before: #29220 #37423. I believe this is one of the many things blocked by #41619.

@aidanhs aidanhs added A-impl-trait Area: `impl Trait`. Universally / existentially quantified anonymous types with static dispatch.
