Would it make sense to setup an example to explain Expression.field/constant are just static functions you can import directly, then update the following examples without Expression. to make it more concise?

Done. I think we can leave out the example and assume devs will know how to import it unless we start getting questions otherwise.

Why is this called creatingIndexes? I imagine the context text to explain this will be from difference source?

The context is in the commented link above the file: https://cloud.google.com/firestore/docs/pipeline/overview#creating_indexes
It's just an example of a pipeline that would benefit from the creation of a particular index.

People probably dont know what "name" is, you can use FieldPath.documentId() instead.

It doesn't seem to let me do FieldPath.documentId().descending(), maybe because FieldPath isn't an Expression?
