For an object store backend, none of the suggestions in this paragraph
make much sense. "May" is much softer, in terms of

cloud server implementation does not do any of these things.
* Add support for cloud sync, specifically GCP
This adds generic support for sync to cloud services, with specific
spuport for GCP. Adding others -- so long as they support a
compare-and-set operation -- should be comparatively straightforward.
The cloud support includes cleanup of unnecessary data, and should keep
total space usage roughly proportional to the number of tasks.

word for it than "key".
