      SERVER-67246 unlocked the ability for the oplog capped size to be anything, not just a multiple of 256. This blocks fresh installs from downgrading.
      I think we should fix this by adjusting the oplog cap size algorithm to go back to rounding to the nearest 256. This will avoid problems with on-prem LTS users on 7.0 downgrading to 6.0.
