FR: Add capability to send local gzipped files as compressed and have them decompressed (and stored as such) in GCS.

I think it would be helpful to be able to unzip files in my google bucket through gsutil

I see the -Z option Applies gzip content-encoding to file uploads

I would have no problem paying some for added flexibility or file size limitations, but I need to unzip from 50GB ZIP to 1TB GZ, in my case.

Start by clarifying whether this requests local gzip uploads, decompression of objects already in Google Cloud Storage, or conversion from ZIP to gzip. Review gsutil's -Z upload behavior and command entry points, then define the supported inputs, output encoding, and handling of very large files before implementation. Done requires an agreed workflow and tests for the selected behavior.
