Status of project?

I am just learning about spanner change streams today, and from what I can gather, one can gather the events from the stream using Spanner's API:

• https://pkg.go.dev/cloud.google.com/go/spanner/apiv1#Client.ExecuteStreamingSql
• https://docs.cloud.google.com/spanner/docs/change-streams/details#change_stream_query_syntax

Does that mean that the changestreams library in this repository is obsolete? If not, how is it better/different?
