Looks nice! Will want to have @devsjc have a look before merging it too, but yeah, just one more change to remove fsspec from the codebase for GCP as well please.
- Replace gcsfs with obstore FsspecStore for GCS - Remove gcsfs dependency as it's no longer needed - All filesystem types (local, S3, GCS) now use obstore - Addresses maintainer feedback in PR review
