This probably won't work well, as it would remove the feature for older API versions (which the client supports)
The
keep-storageparameter for the/build/pruneAPI endpoint was deprecated in favor ofreserved-spaceand scheduled for removal in API v1.49. Since the current API version is v1.52, this PR removes the deprecated parameter completely.Changes Made

The removal maintains proper API versioning:

keepStoragefield for backward compatibility, as this is a separate concern from the API parameter.Testing
Added comprehensive test coverage in
