Is there any particular reason for these being defined as type aliases? https://github.com/delta-io/delta-rs/blob/main/rust/src/schema.rs#L14-L20

best guess is legibility. I actually also wondered if they actually help or rather confuse things. But then I also was never bohered enough to do something about it 😄

If any of those types change the aliases make it easier to update

Heh, guess I was bothered enough https://github.com/delta-io/delta-rs/pull/1388/files
