Here is a scenario:
1. `resolveFrostFSErrors` is false.
2. The first object part was not written, which was signified in status.
3. The second part was written correctly.
Client now thinks that the object is written even though it was not.
In theory we could also return only status, but client-side splitting
is not a single RPC, so it makes sense.
