I think this is a bug with the config block feature. We currently apply
this at the storage plugin level, but it does not appear that we are
sourcing this configuration from the writers and instead creating a new
configuration in each of our three current record writers. I have filed
this bug to investigate the current design further and fix the bug [1].
